- The prefix mis- means wrong. If place means put something somewhere, what does misplace mean?
Answer: put something in the wrong place
This question tests determining meanings of words with affixes (CCSS.L.3.4.b). The word misplace has the prefix mis- added to the base word place. Knowing what both parts mean helps us figure out the whole word. Affixes are word parts added to base words that change their meaning. Prefixes go at the beginning (un-happy, mis-spell). The prefix mis- means 'wrong' or 'badly,' so when we add it to a base word, it means doing that action incorrectly. In this word, the base word is place which means put something somewhere. The prefix is mis- which means wrong. To find the whole word's meaning, we combine these: wrong + put something somewhere = put something in the wrong place. Choice A is correct because it properly combines the meanings. Place means put something somewhere and mis- means wrong, so misplace means to put something in the wrong place or lose track of where you put it. This follows the pattern for mis-: misspell (spell wrong), misbehave (behave wrong), misunderstand (understand wrong). Choice B is incorrect because it confuses mis- (wrong) with re- (again). Students make this error when they mix up different prefix meanings. To help students: Teach common prefixes and their meanings. Practice breaking words into parts: base word + prefix. Strategy: (1) Cover the prefix, identify base word and its meaning. (2) Uncover prefix, identify what it means. (3) Combine: prefix meaning + base meaning = new word meaning. Examples: mis (wrong) + place (put somewhere) = misplace (put in wrong place). mis (wrong) + spell = misspell (spell wrong). Practice with word families (misplace, misspell, misbehave - all mis- meaning wrong).
- The suffix -er can mean "person who." If teach means to help someone learn, what does teacher mean?
Answer: person who teaches
Adding "-er" to "teach" makes "teacher," which means a person who teaches. Choice B is correct. Choice A is like "-er" for comparing (more), Choice C is like "re-," and Choice D is like "-less," so none matches "teach" plus "-er" meaning a person.
- The suffix -ly means in a certain way. If quick means fast, what does quickly mean?
Answer: in a fast way
This question tests determining meanings of words with affixes (CCSS.L.3.4.b). The word 'quickly' has the suffix '-ly' added to the base word 'quick'. Knowing what both parts mean helps us figure out the whole word. Suffixes are word parts added to the end of base words that change their meaning. The suffix '-ly' means 'in a certain way' or 'in the manner of' - we see this in words like slowly (in a slow way), quietly (in a quiet way), and happily (in a happy way). In this word, the base word is 'quick' which the question tells us means 'fast'. The suffix is '-ly' which means 'in that way'. To find the whole word's meaning, we combine these: in a fast way = in a fast way. Choice A is correct because it properly combines the meanings. 'Quick' means fast and '-ly' means in that way, so 'quickly' means in a fast way. This follows the pattern for '-ly': it turns describing words into words that tell how something is done. Choice D is incorrect because it confuses '-ly' with '-ful' which means 'full of'. Students make this error when they don't understand that -ly creates adverbs (how words) not adjectives (describing words). To help students: Teach that -ly turns adjectives into adverbs (tells HOW something is done). Practice strategy: (1) Cover '-ly', identify 'quick' means fast. (2) Uncover '-ly', identify it means 'in that way'. (3) Combine: quick + in that way = in a fast way. Use movement examples: walk slowly, run quickly, speak softly, laugh loudly. Watch for students confusing -ly (in that way) with other suffixes like -ful or -less.
- The suffix -er means person who. If teach means help someone learn, what does teacher mean?
Answer: person who teaches
This question tests determining meanings of words with affixes (CCSS.L.3.4.b). The word teacher has the suffix -er added to the base word teach. Knowing what both parts mean helps us figure out the whole word. Affixes are word parts added to base words that change their meaning. Prefixes go at the beginning (un-happy, re-write). Suffixes go at the end (care-ful, help-less). Common prefixes: un- (not), re- (again), pre- (before), dis- (not), mis- (wrong). Common suffixes: -ful (full of), -less (without), -er (person who), -ly (in that way), -ness (state of being), -able (can be). When you know the base word meaning and the affix meaning, you can figure out the new word meaning. In this word, the base word is teach which means help someone learn. The suffix is -er which means person who. To find the whole word's meaning, we combine these: person who + teach. Choice B is correct because it properly combines the meanings. Teach means help someone learn and -er means person who, so teacher means person who teaches. This follows the pattern for -er: person who + base. Choice C is incorrect because it doesn't apply the affix meaning correctly and uses the meaning for re- instead of -er. Students make this error when they confuse prefixes with suffixes or similar affixes. To help students: Teach common affixes and their meanings. Practice breaking words into parts: base word + affix. Strategy: (1) Cover the affix, identify base word and its meaning. (2) Uncover affix, identify what it means. (3) Combine: base meaning + affix meaning = new word meaning. Examples: un (not) + happy (glad) = unhappy (not glad). re (again) + write (put words) = rewrite (put words again). care (concern) + ful (full of) = careful (full of concern). care (concern) + less (without) = careless (without concern). Practice with word families (unhappy, unkind, unlock - all un- meaning not). Watch for: confusing un- and re- / ignoring the affix / not combining meanings / wrong affix definition.
- The prefix dis- means not. If agree means think the same, what does disagree mean?
Answer: not think the same
This question tests determining meanings of words with affixes (CCSS.L.3.4.b). The word disagree has the prefix dis- added to the base word agree. Knowing what both parts mean helps us figure out the whole word. Affixes are word parts added to base words that change their meaning. Prefixes go at the beginning (un-happy, re-write). Suffixes go at the end (care-ful, help-less). Common prefixes: un- (not), re- (again), pre- (before), dis- (not), mis- (wrong). Common suffixes: -ful (full of), -less (without), -er (person who), -ly (in that way), -ness (state of being), -able (can be). When you know the base word meaning and the affix meaning, you can figure out the new word meaning. In this word, the base word is agree which means think the same. The prefix is dis- which means not. To find the whole word's meaning, we combine these: not + agree. Choice B is correct because it properly combines the meanings. Agree means think the same and dis- means not, so disagree means not think the same. This follows the pattern for dis-: not + base. Choice A is incorrect because it doesn't apply the affix meaning correctly and uses the meaning for re- instead of dis-. Students make this error when they confuse similar affixes like dis- and re-. To help students: Teach common affixes and their meanings. Practice breaking words into parts: base word + affix. Strategy: (1) Cover the affix, identify base word and its meaning. (2) Uncover affix, identify what it means. (3) Combine: base meaning + affix meaning = new word meaning. Examples: un (not) + happy (glad) = unhappy (not glad). re (again) + write (put words) = rewrite (put words again). care (concern) + ful (full of) = careful (full of concern). care (concern) + less (without) = careless (without concern). Practice with word families (unhappy, unkind, unlock - all un- meaning not). Watch for: confusing un- and re- / ignoring the affix / not combining meanings / wrong affix definition.
- The suffix -less means without. If hope means wishing, what does hopeless mean?
Answer: without hope
This question tests determining meanings of words with affixes (CCSS.L.3.4.b). The word hopeless has the suffix -less added to the base word hope. Knowing what both parts mean helps us figure out the whole word. Affixes are word parts added to base words that change their meaning. Prefixes go at the beginning (un-happy, re-write). Suffixes go at the end (care-ful, help-less). Common prefixes: un- (not), re- (again), pre- (before), dis- (not), mis- (wrong). Common suffixes: -ful (full of), -less (without), -er (person who), -ly (in that way), -ness (state of being), -able (can be). When you know the base word meaning and the affix meaning, you can figure out the new word meaning. In this word, the base word is hope which means wishing. The suffix is -less which means without. To find the whole word's meaning, we combine these: without + hope. Choice B is correct because it properly combines the meanings. Hope means wishing and -less means without, so hopeless means without hope. This follows the pattern for -less: without + base. Choice A is incorrect because it doesn't apply the affix meaning correctly and uses the meaning for -ful instead of -less. Students make this error when they confuse similar affixes like -less and -ful. To help students: Teach common affixes and their meanings. Practice breaking words into parts: base word + affix. Strategy: (1) Cover the affix, identify base word and its meaning. (2) Uncover affix, identify what it means. (3) Combine: base meaning + affix meaning = new word meaning. Examples: un (not) + happy (glad) = unhappy (not glad). re (again) + write (put words) = rewrite (put words again). care (concern) + ful (full of) = careful (full of concern). care (concern) + less (without) = careless (without concern). Practice with word families (unhappy, unkind, unlock - all un- meaning not). Watch for: confusing un- and re- / ignoring the affix / not combining meanings / wrong affix definition.
- The suffix -less means without. If hope means wanting something good, what does hopeless mean?
Answer: without hope
This question tests determining meanings of words with affixes (CCSS.L.3.4.b). The word 'hopeless' has the suffix '-less' added to the base word 'hope'. Knowing what both parts mean helps us figure out the whole word. Suffixes are word parts added to the end of base words that change their meaning. The suffix '-less' means 'without' - we see this in words like careless (without care), fearless (without fear), and helpless (without help). In this word, the base word is 'hope' which the question tells us means 'wanting something good'. The suffix is '-less' which means 'without'. To find the whole word's meaning, we combine these: without + wanting something good = without hope. Choice C is correct because it properly combines the meanings. 'Hope' means wanting something good and '-less' means without, so 'hopeless' means without hope. This follows the pattern for '-less': it means lacking or not having what the base word describes. Choice A is incorrect because it confuses '-less' with '-ful' which means 'full of'. Students make this error when they mix up opposite suffixes or don't know what '-less' means. To help students: Teach suffix pairs that are opposites: -ful (full of) vs -less (without). Practice strategy: (1) Cover '-less', identify 'hope' and its meaning. (2) Uncover '-less', identify it means 'without'. (3) Combine: hope + without = without hope. Create word pairs: hopeful/hopeless, careful/careless, helpful/helpless. Watch for students confusing -less (without) with -ful (full of) since they're opposites.
- The suffix -less means without. If hope means wishing, what does hopeless mean?
Answer: without hope
This question tests determining meanings of words with affixes (CCSS.L.3.4.b). The word 'hopeless' has the suffix '-less' added to the base word 'hope'. Knowing what both parts mean helps us figure out the whole word. Affixes are word parts added to base words that change their meaning. Suffixes go at the end (care-ful, help-less). The suffix '-less' is a common suffix that means 'without' or 'lacking'. The question provides this meaning. In this word, the base word is 'hope' which means wishing or expecting something positive. The suffix is '-less' which means 'without'. To find the whole word's meaning, we combine these: hope + without = without hope. Choice C is correct because it properly combines the meanings. 'Hope' means wishing and '-less' means 'without', so 'hopeless' means 'without hope' or having no expectation of success. This follows the pattern for '-less': it shows the absence of the base word's quality. Choice A is incorrect because it confuses '-less' with '-ful' which means 'full of'. Students make this error when they mix up opposite suffixes. To help students: Teach common suffixes and their meanings. Practice breaking words into parts: base word + suffix. Strategy: (1) Cover the suffix, identify 'hope' means wishing. (2) Uncover suffix '-less', remember it means 'without'. (3) Combine: hope + without = without hope. Examples: care + less = careless (without care), fear + less = fearless (without fear). Watch for: confusing -less (without) and -ful (full of) - they're opposites.
- The suffix -er means person who does. If teach means help someone learn, what does teacher mean?
Answer: person who teaches
This question tests determining meanings of words with affixes (CCSS.L.3.4.b). The word teacher has the suffix -er added to the base word teach. Knowing what both parts mean helps us figure out the whole word. Affixes are word parts added to base words that change their meaning. Suffixes go at the end (help-er, work-er). The suffix -er means 'person who does' or 'one who,' so when we add it to a verb, it creates a noun naming the person who does that action. In this word, the base word is teach which means help someone learn. The suffix is -er which means person who does. To find the whole word's meaning, we combine these: teach (help someone learn) + er (person who) = person who helps someone learn. Choice B is correct because it properly combines the meanings. Teach means help someone learn and -er means person who does, so teacher means person who teaches or helps others learn. This follows the pattern for -er: helper (person who helps), worker (person who works), singer (person who sings). Choice A is incorrect because it doesn't recognize -er as meaning 'person who' and instead treats it like a comparison suffix. Students make this error when they confuse the two uses of -er. To help students: Teach common suffixes and their meanings. Practice breaking words into parts: base word + suffix. Strategy: (1) Cover the suffix, identify base word and its meaning. (2) Uncover suffix, identify what it means. (3) Combine: base meaning + suffix meaning = new word meaning. Examples: teach (help learn) + er (person who) = teacher (person who teaches). help + er = helper (person who helps). Practice with word families (teacher, helper, worker - all -er meaning person who).
- The suffix -ful means full of. If help means to give support, what does helpful mean?
Answer: full of help
This question tests determining meanings of words with affixes (CCSS.L.3.4.b). The word 'helpful' has the suffix '-ful' added to the base word 'help'. Knowing what both parts mean helps us figure out the whole word. Suffixes are word parts added to the end of base words that change their meaning. The suffix '-ful' means 'full of' or 'having a lot of' - we see this in words like careful (full of care), beautiful (full of beauty), and joyful (full of joy). In this word, the base word is 'help' which the question tells us means 'to give support'. The suffix is '-ful' which means 'full of'. To find the whole word's meaning, we combine these: full of + giving support = full of help. Choice B is correct because it properly combines the meanings. 'Help' means to give support and '-ful' means full of, so 'helpful' means full of help. This follows the pattern for '-ful': it means having the quality of the base word. Choice A is incorrect because it confuses '-ful' with '-less' which means 'without' - these are opposite suffixes. Students make this error when they mix up suffix meanings or don't know that -ful and -less are opposites. To help students: Teach suffix pairs as opposites: -ful (full of) vs -less (without). Practice strategy: (1) Cover '-ful', identify 'help' means support. (2) Uncover '-ful', identify it means 'full of'. (3) Combine: help + full of = full of help. Create word pairs showing opposites: helpful/helpless, careful/careless, hopeful/hopeless. Watch for students confusing -ful (full of) with -less (without).
- The prefix re- means again. What does reread mean?
Answer: read again
This question tests determining meanings of words with affixes (CCSS.L.3.4.b). The word reread has the prefix re- added to the base word read. Knowing what both parts mean helps us figure out the whole word. Affixes are word parts added to base words that change their meaning. Prefixes go at the beginning (un-happy, re-write). The prefix re- means 'again,' so when we add it to a base word, it means doing that action again. In this word, the base word is read which means to look at and understand written words. The prefix is re- which means again. To find the whole word's meaning, we combine these: again + read = read again. Choice A is correct because it properly combines the meanings. Read means to look at and understand written words and re- means again, so reread means read again. This follows the pattern for re-: redo (do again), rewrite (write again), replay (play again). Choice B is incorrect because it uses the wrong prefix meaning - pre- means before, not re-. Students make this error when they confuse similar prefixes. To help students: Teach common prefixes and their meanings. Practice breaking words into parts: base word + prefix. Strategy: (1) Cover the prefix, identify base word and its meaning. (2) Uncover prefix, identify what it means. (3) Combine: prefix meaning + base meaning = new word meaning.
- The suffix -ness means state of being. If happy means glad, what is happiness?
Answer: state of being happy
This question tests determining meanings of words with affixes (CCSS.L.3.4.b). The word 'happiness' has the suffix '-ness' added to the base word 'happy'. Knowing what both parts mean helps us figure out the whole word. Affixes are word parts added to base words that change their meaning. Suffixes go at the end (care-ful, help-less). The suffix '-ness' is a common suffix that means 'state of being' or 'quality of'. The question tells us this meaning. In this word, the base word is 'happy' which means glad or joyful. The suffix is '-ness' which means 'state of being'. To find the whole word's meaning, we combine these: happy + state of being = state of being happy. Choice C is correct because it properly combines the meanings. 'Happy' means glad and '-ness' means 'state of being', so 'happiness' means 'state of being happy'. This follows the pattern for '-ness': it turns adjectives into nouns describing a condition or quality. Choice D is incorrect because it confuses '-ness' with '-ful' which means 'full of'. Students make this error when they don't understand that '-ness' creates abstract nouns. To help students: Teach common suffixes and their meanings. Practice breaking words into parts: base word + suffix. Strategy: (1) Cover the suffix, identify 'happy' means glad. (2) Uncover suffix '-ness', remember it means 'state of being'. (3) Combine: happy + state of being = state of being happy. Examples: kind + ness = kindness (state of being kind), dark + ness = darkness (state of being dark). Watch for: not recognizing -ness creates abstract nouns about states or qualities.
- The suffix -less means without. If help means aid, what does helpless mean?
Answer: without help
This question tests determining meanings of words with affixes (CCSS.L.3.4.b). The word helpless has the suffix -less added to the base word help. Knowing what both parts mean helps us figure out the whole word. Affixes are word parts added to base words that change their meaning. Prefixes go at the beginning (un-happy, re-write). Suffixes go at the end (care-ful, help-less). Common prefixes: un- (not), re- (again), pre- (before), dis- (not), mis- (wrong). Common suffixes: -ful (full of), -less (without), -er (person who), -ly (in that way), -ness (state of being), -able (can be). When you know the base word meaning and the affix meaning, you can figure out the new word meaning. In this word, the base word is help which means aid. The suffix is -less which means without. To find the whole word's meaning, we combine these: without + help. Choice C is correct because it properly combines the meanings. Help means aid and -less means without, so helpless means without help. This follows the pattern for -less: without + base. Choice A is incorrect because it doesn't apply the affix meaning correctly and uses the meaning for -ful instead of -less. Students make this error when they confuse similar affixes like -ful and -less. To help students: Teach common affixes and their meanings. Practice breaking words into parts: base word + affix. Strategy: (1) Cover the affix, identify base word and its meaning. (2) Uncover affix, identify what it means. (3) Combine: base meaning + affix meaning = new word meaning. Examples: un (not) + happy (glad) = unhappy (not glad). re (again) + write (put words) = rewrite (put words again). care (concern) + ful (full of) = careful (full of concern). care (concern) + less (without) = careless (without concern). Practice with word families (unhappy, unkind, unlock - all un- meaning not). Watch for: confusing un- and re- / ignoring the affix / not combining meanings / wrong affix definition.
- The suffix -less means without. If help means support, what does helpless mean?
Answer: without help
Adding "-less" to "help" makes "helpless," which means without help. Choice C is correct. Choice A is like "-ful," Choice B is like "-er" (a person), and Choice D is like "re-," so none matches "help" plus "-less."
- If kind means nice, what does unkind mean?
Answer: not nice
This question tests determining meanings of words with affixes (CCSS.L.3.4.b). The word 'unkind' has the prefix 'un-' added to the base word 'kind'. Knowing what both parts mean helps us figure out the whole word. Prefixes are word parts added to the beginning of base words that change their meaning. The prefix 'un-' means 'not' or 'opposite of' - we see this in words like unhappy (not happy), unfair (not fair), and untrue (not true). In this word, the base word is 'kind' which the question tells us means 'nice'. The prefix is 'un-' which means 'not'. To find the whole word's meaning, we combine these: not + nice = not nice. Choice B is correct because it properly combines the meanings. 'Kind' means nice and 'un-' means not, so 'unkind' means not nice. This follows the pattern for 'un-': it creates the opposite meaning of the base word. Choice D is incorrect because it confuses 'unkind' with 'kindness' - it uses the wrong word form and adds a different meaning. Students make this error when they focus only on the base word 'kind' and ignore the prefix. To help students: Teach that un- always means 'not' or 'opposite'. Practice strategy: (1) Cover 'un-', identify 'kind' means nice. (2) Uncover 'un-', identify it means 'not'. (3) Combine: not + nice = not nice. Create word pairs showing opposites: happy/unhappy, safe/unsafe, kind/unkind. Watch for students ignoring the prefix or confusing un- (not) with re- (again).
- The prefix mis- means wrong. What does misplace mean?
Answer: place something in the wrong spot
This question tests determining meanings of words with affixes (CCSS.L.3.4.b). The word misplace has the prefix mis- added to the base word place. Knowing what both parts mean helps us figure out the whole word. Affixes are word parts added to base words that change their meaning. Prefixes go at the beginning (un-happy, re-write). Suffixes go at the end (care-ful, help-less). Common prefixes: un- (not), re- (again), pre- (before), dis- (not), mis- (wrong). Common suffixes: -ful (full of), -less (without), -er (person who), -ly (in that way), -ness (state of being), -able (can be). When you know the base word meaning and the affix meaning, you can figure out the new word meaning. In this word, the base word is place which means to put something in a spot. The prefix is mis- which means wrong. To find the whole word's meaning, we combine these: wrong + place. Choice A is correct because it properly combines the meanings. Place means to put something in a spot and mis- means wrong, so misplace means place something in the wrong spot. This follows the pattern for mis-: wrong + base. Choice B is incorrect because it doesn't apply the affix meaning correctly and uses the meaning for re- instead of mis-. Students make this error when they confuse similar affixes like mis- and re-. To help students: Teach common affixes and their meanings. Practice breaking words into parts: base word + affix. Strategy: (1) Cover the affix, identify base word and its meaning. (2) Uncover affix, identify what it means. (3) Combine: base meaning + affix meaning = new word meaning. Examples: un (not) + happy (glad) = unhappy (not glad). re (again) + write (put words) = rewrite (put words again). care (concern) + ful (full of) = careful (full of concern). care (concern) + less (without) = careless (without concern). Practice with word families (unhappy, unkind, unlock - all un- meaning not). Watch for: confusing un- and re- / ignoring the affix / not combining meanings / wrong affix definition.
- If kind means nice, what does unkind mean?
Answer: not nice
This question tests determining meanings of words with affixes (CCSS.L.3.4.b). The word unkind has the prefix un- added to the base word kind. Knowing what both parts mean helps us figure out the whole word. Affixes are word parts added to base words that change their meaning. Prefixes go at the beginning (un-happy, re-write). The prefix un- means 'not' or 'opposite of,' so when we add it to a base word, it creates the opposite meaning. In this word, the base word is kind which means nice or caring. The prefix is un- which means not. To find the whole word's meaning, we combine these: not + nice = not nice. Choice B is correct because it properly combines the meanings. Kind means nice and un- means not, so unkind means not nice. This follows the pattern for un-: unhappy (not happy), unfair (not fair), unsafe (not safe). Choice A is incorrect because it uses the wrong prefix meaning - re- means again, not un-. Students make this error when they don't know the correct prefix meaning. To help students: Teach common prefixes and their meanings. Practice breaking words into parts: base word + prefix. Strategy: (1) Cover the prefix, identify base word and its meaning. (2) Uncover prefix, identify what it means. (3) Combine: prefix meaning + base meaning = new word meaning. Examples: un (not) + happy (glad) = unhappy (not glad).
- The prefix dis- means not or opposite. If agree means to think the same, what does disagree mean?
Answer: not think the same
Adding "dis-" to "agree" makes "disagree," which means to not think the same. Choice C is correct. Choice A is like "re-" (again), Choice B is like "-ful," and Choice D is like "pre-" (before), so none matches "dis-" plus "agree."
- The prefix mis- means wrong. What does misspell mean?
Answer: spell wrong
This question tests determining meanings of words with affixes (CCSS.L.3.4.b). The word 'misspell' has the prefix 'mis-' added to the base word 'spell'. Knowing what both parts mean helps us figure out the whole word. Affixes are word parts added to base words that change their meaning. Prefixes go at the beginning (un-happy, re-write). The prefix 'mis-' is a common prefix that means 'wrong' or 'badly'. The question provides this meaning. In this word, the base word is 'spell' which means to write or say the letters of a word correctly. The prefix is 'mis-' which means 'wrong'. To find the whole word's meaning, we combine these: wrong + spell = spell wrong. Choice A is correct because it properly combines the meanings. 'Spell' means to write letters correctly and 'mis-' means 'wrong', so 'misspell' means 'spell wrong' or spell incorrectly. This follows the pattern for 'mis-': it indicates doing something incorrectly. Choice B is incorrect because it confuses 'mis-' with 're-' which means 'again'. Students make this error when they don't know the specific meaning of 'mis-'. To help students: Teach common prefixes and their meanings. Practice breaking words into parts: base word + prefix. Strategy: (1) Cover the prefix, identify 'spell' as the base. (2) Uncover prefix 'mis-', remember it means 'wrong'. (3) Combine: wrong + spell = spell wrong. Examples: mis + understand = misunderstand (understand wrong), mis + place = misplace (place wrong). Watch for: confusing mis- (wrong) with other prefixes.
- The prefix re- means again. What does reread mean?
Answer: read again
This question tests determining meanings of words with affixes (CCSS.L.3.4.b). The word reread has the prefix re- added to the base word read. Knowing what both parts mean helps us figure out the whole word. Affixes are word parts added to base words that change their meaning. Prefixes go at the beginning (un-happy, re-write). The prefix re- means 'again,' so when we add it to a base word, it means doing that action again. In this word, the base word is read which means to look at and understand written words. The prefix is re- which means again. To find the whole word's meaning, we combine these: again + read = read again. Choice A is correct because it properly combines the meanings. Read means to look at and understand written words and re- means again, so reread means to read again. This follows the pattern for re-: redo (do again), rewrite (write again), replay (play again). Choice D is incorrect because it adds a meaning (very fast) that isn't part of either the base word or the prefix. Students make this error when they guess instead of using the actual affix meaning. To help students: Teach common prefixes and their meanings. Practice breaking words into parts: base word + prefix. Strategy: (1) Cover the prefix, identify base word and its meaning. (2) Uncover prefix, identify what it means. (3) Combine: prefix meaning + base meaning = new word meaning. Examples: re (again) + read = reread (read again). re (again) + do = redo (do again). Practice with word families (reread, rewrite, redo - all re- meaning again).
