- Determine the meaning of the word microscope by analyzing its word parts.
Answer: A device for looking closely at things that are very small
The root "micro" means small, and the root "scope" means to see or look. Put together, they name a device for looking closely at things that are very small—exactly what a microscope is used for. The choice about a handheld tool for seeing far-away objects uses the "look" idea but points to something distant, which reverses "micro" (small); that describes a telescope instead. The choice about measuring distance between far-apart objects ignores "scope" entirely and focuses on distance rather than seeing. The choice about making tiny sketches includes the idea of small, but "scope" means to look, not to draw, so it misses the tool's real purpose.
- Which pair of words shares the Latin root vid/vis, meaning "see"?
Answer: visible and evidence
The root "vid/vis" means "see." Both "visible" (able to be seen) and "evidence" (something shown to be true) carry this root, so this pair is correct. In the pair with "audience" and "porthole," the words come from different roots: "aud" (hear) and "port" (carry), so they don't share "vid/vis." In the pair with "export" and "audible," the roots are again split: "port" (carry) and "aud" (hear). In the pair with "phonics" and "provision," "phonics" uses "phon" (sound), and only "provision" contains "vis"—since the two words don't share the same root, this pair fails the question's ask. To answer, you must know that "vid/vis" means "see" and check that BOTH words in a pair truly carry it.
- In a nonfiction article, the author uses the word biography. Based on the roots, what is a biography?
Answer: A written account describing the events of a person's life
To define this word, break it into its roots. The root 'bio' means life, and the root 'graph' means write, so 'biography' literally means 'life writing.' That points directly to the choice describing a written account of the events of a person's life. The choice about measuring how far a person has traveled focuses on distance, which comes from meter-type roots, not from 'bio' or 'graph.' The choice about a list of words paired with their meanings describes a dictionary or glossary; while it involves writing, it has nothing to do with 'life.' The choice about capturing and storing spoken sound mixes in the root 'phon' (sound), so it ignores the meaning of 'bio.' Only one option combines both roots correctly: writing ('graph') about a life ('bio').
- Break Word into Parts: Break interrupt into word parts and use the root meanings to choose the best definition.
Answer: inter- (between) + rupt (break) = to break in between; to stop something briefly
The word 'interrupt' splits into the prefix inter-, meaning 'between,' and the root rupt, meaning 'break' (the same root you see in erupt and disrupt). Put together, they mean 'to break in between'—to break into something while it is happening and stop it briefly. That is exactly what happens when you interrupt a conversation. The other options all use the correct prefix inter-, but each pairs it with the wrong root. The choice using terr ('earth') builds a definition about land, but 'interrupt' has nothing to do with earth. The choice using script ('write') describes writing between lines, but there is no writing root in this word. The choice using port ('carry') describes moving things between places, but 'interrupt' does not contain a carrying root. Since only rupt ('break') actually appears in 'interrupt,' the definition about breaking in between is the single best answer.
- Determine Meaning Using Root: A coach tells a player not to misjudge the situation. Knowing the prefix mis- means "wrong," what does misjudge mean?
Answer: To judge something incorrectly
To find the meaning of misjudge, break the word into its parts: the prefix mis- plus the base word judge. Since mis- means "wrong" or "badly," misjudge means to judge something incorrectly—to form a wrong opinion or assessment, like misjudging a person's character or the distance to catch a ball. This fits the coach's warning about making a wrong judgment. "To judge something over again" describes the prefix re- (as in rewrite or return), which means "again," not "wrong." "To judge before knowing the facts" describes the prefix pre- (as in preview or precede), which means "before," not "wrong." "To judge in place of someone else" describes the idea of a substitute (like sub-), which has nothing to do with the prefix mis-. Only mis- adds the meaning of error or wrongness, so misjudge means to judge incorrectly.
- In the word manuscript, which root means "write"?
Answer: script, meaning "write"
The word "manuscript" breaks into "manu" and "script." The root "script" comes from Latin and means "write," so it is the correct answer. The root "manu" is really part of the word, but it means "hand" (as in "manual"), not "write." The root "scrib" is a real writing-related root found in words like "scribble" and "describe," but it does not appear in "manuscript," and it does not mean "book." The piece "cript" is not a true root at all—it just looks like part of "script" broken off—and it has nothing to do with "secret." Only "script" both appears in "manuscript" and means "write."
- Identify Root and Meaning: In the word microphone, what does the Greek root phon mean?
Answer: Sound, as in the noise a device picks up or plays
The word 'microphone' breaks into micro (small) and phon (sound), so it names a device that captures sound. The root phon consistently means 'sound,' which you can see in telephone (sound from far away), phonics (studying speech sounds), and symphony (sounds played together)—so the choice tying phon to sound is correct. 'Light' names the meaning of a different root, photo, found in photograph and photosynthesis; it isn't part of 'microphone.' 'Measure' matches the root meter, seen in thermometer and perimeter, not phon. 'Small' is tempting because it's a real meaning inside 'microphone'—but it belongs to the prefix micro, not to the root phon the question asks about. Once you know phon = sound, you can unlock many words: cacophony, phonograph, and polyphonic (poly + phon + ic, 'having many sounds').
- Determine Meaning Using Root: The word transport contains the Latin root port, meaning "carry." Based on the parts trans (across) + port (carry), what does transport most likely mean?
Answer: To carry something across from one place to another
The prefix trans- means "across" and the root port means "carry," so transport means to carry something across from one place to another. The other choices all correctly use the root port ("carry"), but they attach the wrong prefix meaning. "Carry back to where it started" fits the prefix re- ("back, again"), as in return, not trans-. "Carry down below its original position" fits the prefix de- ("down"), as in descend, not trans-. "Carry around a single central point" fits the prefix circum- ("around"), as in circle, not trans-. To choose correctly, break the word into its parts, recall each meaning, and combine them: trans (across) + port (carry) = carry across. Only "carry across from one place to another" matches both parts of the actual word transport.
- Using the root meanings, what does telescope most likely mean? (tele = "far" and scope = "see/view")
Answer: A device used to see something far away
The root tele means "far" and the root scope means "see" or "view," so combining them points to a device for seeing something that is far away. The choice about measuring how far away something is keeps the "far" idea but replaces "see" with measuring distance. The choice about sending signals far away swaps the "see" root for the idea of transmitting, which fits a word like telephone, not telescope. The choice about recording events far away also drops "see" and adds recording, an action neither root names. Each wrong answer keeps "far" but loses the "see/view" meaning that scope requires, so the best answer is the device used to see something far away.
- What is the root in transport, and what does it mean?
Answer: port, meaning "carry"
The word transport breaks into the prefix trans- and the root port, which comes from the Latin for "carry." That meaning fits perfectly: to transport something is to carry it from one place to another, so port meaning "carry" is correct. The choice trans meaning "before" is actually a prefix, not a root, and its real meaning is "across," not "before," so it misses on two counts. The choice tran meaning "change" is a cut-off piece of the prefix trans-; it is not a real root and "change" is not its meaning. The choice sport meaning "send" grabs real-looking letters from the middle of the word, but sport is not the root inside transport, and the meaning "send" belongs to a different root (mit/mis), not to port. Only port carries both the correct root and the correct meaning "carry."
- Apply Root Knowledge: Using what you know about Greek and Latin roots and prefixes, what does the word disrupt most likely mean?
Answer: To break apart; to interrupt or throw a normal flow into disorder
The prefix dis- means 'apart' or 'away,' and the root rupt means 'break.' Combining them, disrupt means 'to break apart'—to interrupt a normal flow or throw something into disorder, like disrupting a class or traffic. You can check this by recognizing rupt in related words: interrupt (break in), erupt (break out), and rupture (a break). The choice about advancing toward a distant goal ignores rupt entirely and treats no real prefix-root pair, so it doesn't fit the parts of the word. The choice about joining separate parts together is the opposite of what dis- ('apart') signals, and it also drops the meaning 'break.' The choice about turning under or overturning a ruling borrows the sense of another root and never accounts for rupt ('break'), so it can't be right. Only 'break apart; interrupt or throw into disorder' matches both parts of disrupt: dis- ('apart') plus rupt ('break').
- Apply Root Knowledge: If dict means "speak" or "say" and pre- means "before," what does predict mean?
Answer: To say what will happen before it does
Break the word into its parts: pre- means "before" and dict means "speak" or "say." Putting those together, predict means to say what will happen before it does—like predicting tomorrow's weather. That is exactly the correct choice. "To say the same thing again" uses the prefix re- (again), which describes a word like re-say, not the prefix pre-. "To speak against another person" uses the idea behind the prefix contra- (against), which fits contradict, not predict. "To speak up in place of someone else" describes what happens when you dictate for another person, but it ignores the prefix pre- (before), so it cannot be the meaning of predict. Only the correct choice combines both real parts of the word: pre- (before) + dict (speak/say).
- Using the root meanings of e- and ject, what does eject most likely mean?
Answer: To throw something out
The prefix "e-" means "out" and the root "ject" means "throw," so "eject" means to throw something out—like a machine that ejects a disc. "To throw something out" combines both roots correctly. "To join something together" uses a "together" meaning that belongs to a different prefix (like the "con-" in "conjunction"), not "e-," meaning "out." "To throw something forward" keeps the "throw" idea from "ject" but adds "forward," which would fit a prefix like "pro-" (as in "project"), not "e-." "To bring something back in" points the action inward, the opposite of "e-" meaning "out," and drops the "throw" idea entirely. Only "to throw something out" matches both "out" and "throw" the way "eject" does.
- Find Words with Same Root: Which set of words all share the Greek root graph, meaning "write"?
Answer: photograph, paragraph, autograph
The correct set is photograph, paragraph, and autograph, because each word contains the Greek root graph, meaning "write": photograph = photo (light) + graph, paragraph = para (beside) + graph, and autograph = auto (self) + graph. The other sets are built from a single shared root too, but it is not graph. Telephone, phonics, and symphony all share phon, meaning "sound," so they deal with hearing rather than writing. Biology, biome, and antibiotic all share bio, meaning "life," which points to living things, not writing. Telescope, telephone, and telegram all share tele, meaning "far" or "distant"—telegram even ends in gram (a close cousin of graph), but its shared root is tele, not graph. To answer, look past the beginning of each word and find the piece every word in the set has in common. Only one set has graph in every word. Knowing that graph means "write" also helps you unlock unfamiliar words like biography, telegraph, and seismograph.
- Break the word transportation into parts and use the root meanings to choose the best definition.
Answer: trans-port: to carry across, moving people or goods from one place to another over a distance
The prefix trans- means "across" and the root port means "carry," so transport means to carry something across a distance—which is exactly what transportation does when it moves people or goods from place to place. The choice built on "see across" mistakes port for the root vis/vid, which actually means "see" (as in vision or video). The choice built on "speak across" confuses port with the root dict, meaning "speak" (as in dictate or predict). The choice built on "write across" swaps port for the root scrib/script, meaning "write" (as in describe or manuscript). Each wrong answer keeps the correct prefix but assigns port a meaning that belongs to a different Latin root. Once you know port means "carry," you can unlock related words like portable (able to be carried), import (carry in), and export (carry out).
- Which set of words shares the same Latin root as manuscript, meaning "write"?
Answer: describe, inscription, prescribe
The word manuscript comes from a Latin root meaning "to write." To find the matching set, look for words whose meanings all connect to writing. Describe means to put something into words, an inscription is words written or carved onto a surface, and prescribe means to write out an order or instruction—so this set fits. The set with audience, audible, and auditorium is built on a root meaning "hear," since all three deal with listening or sound reaching your ears. The set with telephone, microphone, and symphony comes from a root meaning "sound," as each involves sound being carried or produced. The set with visible, video, and vision comes from a root meaning "see," since all three relate to sight. Only the writing-related set matches manuscript.
- Identify Root and Meaning: In the word predict, what is the root, and what does it mean? (Hint: pre- means "before.")
Answer: dict — "speak/say," the part that carries the word's core meaning
To find the root, split the word into meaningful parts. 'Predict' breaks into the prefix pre- ("before") plus the root dict ("speak/say"), so predict means to speak or say something beforehand. The root is dict, the part that carries the word's core meaning, which is why saying dict means "speak/say" is correct. You can see this same root in dictate, dictionary, and contradict. Choosing pre- confuses the prefix with the root; pre- attaches to the front and only adds "before," it is not the base word. Choosing ict wrongly treats a leftover string of letters as a meaningful part; once you remove pre-, the true root is dict, not ict, and "the result of" is not its meaning. Choosing pred also breaks the word in the wrong place and invents the meaning "early"; the actual boundary falls between pre- and dict, so pred is not a real root here. Splitting a word at the correct boundary and knowing the root's meaning lets you unlock many unfamiliar words.
- If pre means "before" and dict means "speak," what does predict most likely mean?
Answer: To say beforehand what is likely to happen.
The word part "pre" means "before" and "dict" means "speak," so "predict" means to speak about something before it happens—in other words, to say ahead of time what is likely to occur. That matches saying beforehand what is likely to happen. Speaking again about something already said misses the "before" idea and instead points to repeating, which would fit a part like "re-." Speaking out against a decision uses "speak" but adds an "against" meaning that neither root supplies. Speaking forcefully to a large crowd keeps the idea of speaking but drops "before" entirely, describing how loudly someone talks rather than foretelling the future. Only the first choice combines both roots—"before" plus "speak"—so it is the best answer.
- Apply Root Knowledge: The prefix sub means "under," and the root merge means "dip/plunge." Based on these roots, what does submerge most likely mean?
Answer: To plunge something under the surface, sinking it completely underwater
To answer this, break the word into parts and combine their meanings. The prefix sub- means "under," and the root merge means "dip/plunge." Put together, submerge means to plunge something completely under the surface—to sink it underwater. That is exactly what the correct choice says: to plunge something under, sinking it fully beneath the water. The choice about lowering something only part way is wrong because sub- means fully under, not just dipping the top edge below the surface. The choice about rising up and breaking through the surface reverses the meaning; that describes emerge (e- means "out"), the opposite of submerge. The choice about floating on top without dipping beneath also ignores sub- entirely, since something floating never goes under at all. Only the option that combines "under" and "plunge" matches both roots.
- Apply Root Knowledge: If scrib/script means "write" and pre- means "before," what does prescribe most likely mean?
Answer: To write out directions or orders beforehand, as a doctor does
The word 'prescribe' breaks into pre- (meaning 'before') and scrib (meaning 'write'), so it means to write out directions beforehand—just like a doctor writes a prescription with orders before you take a medicine. That makes 'to write out directions or orders beforehand' the best match. The choice about copying or writing something over again matches the prefix re- ('again'), not pre- ('before'). Writing down words someone speaks out loud describes transcribing, which uses trans- ('across') plus scrib, so the prefix is wrong. Signing your name below an agreement describes subscribing, which uses sub- ('under' or 'below') plus scrib—again the wrong prefix. All four options involve writing, so the root scrib is not enough by itself; you must use the prefix pre- ('before') to land on the correct meaning.
