Question 1

Miguel says: 'Mis hermanos son altos y mis hermanas son   también.'

Miguel wants to say his sisters are 'tall' too. Which word correctly fills the blank, and why?

  1. altos, because Miguel is male and sets the gender for the whole family
  2. alta, because 'hermanas' is feminine but singular agreement is used after son
  3. altas, because 'hermanas' is feminine plural and the adjective must match in both gender and number (correct answer)
  4. alto, because adjectives after ser do not change for gender or number
Explanation: When you see an adjective in Spanish, your first instinct should be to ask two questions: What gender is the noun it describes? and Is that noun singular or plural? Spanish adjectives must agree with their noun in both gender and number — every time, no exceptions. Here, the noun is hermanas — feminine and plural. That means the adjective describing it must also be feminine and plural. The masculine singular form alto becomes alta (feminine singular), altos (masculine plural), or altas (feminine plural). Since hermanas is feminine plural, altas is the only correct match, making C the right answer. Now let's see why the other choices miss the mark. A suggests that Miguel's gender as the speaker controls adjective agreement — this is a common misconception. The speaker's gender is irrelevant; only the noun being described matters. B gets the gender right (alta is correctly feminine) but applies singular agreement to a plural noun, which breaks the number-agreement rule. D claims adjectives after ser are invariable — this is simply false. Adjectives always agree with their subject in Spanish, regardless of whether the linking verb is ser, estar, or anything else. A handy strategy: whenever you see an adjective, draw a quick mental arrow back to the noun it modifies and check off two boxes — gender ✓ and number ✓. If both match, you have your answer. This two-step check will save you on virtually every adjective agreement question in Spanish 1.

Question 2

A teacher writes this sentence on the board and asks students to find the mistake: 'Los niños español hablan muy rápido.'

What is the adjective agreement error in the sentence on the board, and what is the correct form?

  1. español should be española because it follows a plural noun and must take a feminine ending
  2. español should be españolo because adjectives placed before the noun take a different masculine form
  3. español should be españolas because nationality adjectives require a feminine plural form before verbs
  4. español should be españoles because it modifies niños, which is masculine plural (correct answer)
Explanation: Whenever you see a question about adjectives in Spanish, your first instinct should be to check gender and number agreement — every adjective must match the noun it describes in both categories. In the sentence 'Los niños español hablan muy rápido,' the adjective español is modifying niños. Since niños is masculine and plural, the adjective must also be masculine and plural. The masculine plural form of español is españoles — formed by adding -es to the singular form. The corrected sentence reads: Los niños españoles hablan muy rápido. That makes D the right answer. Here's why the other options miss the mark. A claims the adjective should become española, but that's the feminine singular form — it would match a noun like la niña, not los niños. Switching to feminine makes no sense when the noun is masculine. B invents the form españolo, which doesn't exist in Spanish at all. There is no special "pre-noun masculine" form for adjectives — this distractor is designed to confuse you with a false rule. C suggests españolas, the feminine plural form, but again, niños is masculine, so a feminine form is never appropriate here regardless of where the adjective appears or what verb follows. A useful study tip: when checking adjective agreement, always identify the noun's gender and number first, then ask yourself what the adjective ending needs to be. For nationality adjectives ending in a consonant like español, the plural is formed with -es, not just -s.

Question 3

Ana is describing her new apartment to a friend. She says: 'Tengo una mesa   y dos sillas  .'

Ana wants to say her table is 'red' and her chairs are also 'red.' Which option correctly completes both blanks in order?

  1. roja / rojas (correct answer)
  2. rojo / rojos
  3. roja / rojo
  4. rojos / rojas
Explanation: When you see adjectives in Spanish, the first thing to ask yourself is: what noun am I describing, and what is its gender and number? Spanish adjectives must agree with their nouns in both gender (masculine/feminine) and number (singular/plural). The noun mesa (table) is feminine and singular, so it needs a feminine singular adjective: roja. The noun sillas (chairs) is feminine and plural, so it needs a feminine plural adjective: rojas. That makes option A (roja / rojas) the correct choice — both blanks use feminine forms to match their feminine nouns, with the second form pluralized to match sillas. Option B (rojo / rojos) uses masculine forms for both blanks. Since mesa and sillas are both feminine nouns, masculine adjectives are simply the wrong gender — a common mistake if you default to masculine without checking the noun. Option C (roja / rojo) gets the first blank right but uses a masculine singular adjective for sillas, which is both the wrong gender and the wrong number. Option D (rojos / rojas) reverses the logic entirely, applying a masculine plural form to the singular mesa and a correct feminine plural form to sillas — two errors in one. A handy study tip: when memorizing adjective endings, think of the pattern -o / -os / -a / -as for masculine singular, masculine plural, feminine singular, and feminine plural. Train yourself to always identify the noun's gender and number before choosing the adjective form — that one habit will save you from most adjective-agreement mistakes on the exam.

Question 4

Luisa writes in her journal: 'Hoy compré una chaqueta y unos zapatos  .'

Luisa wants to describe only the shoes as 'new' (nuevo/a/os/as). Which form of the adjective correctly fills the blank?

  1. nueva, because zapatos ends in -os and the adjective must use the opposite ending
  2. nuevas, because mixed groups of nouns always take the feminine plural adjective in Spanish
  3. nueva, because chaqueta is feminine and influences the adjective that follows in the sentence
  4. nuevos, because zapatos is masculine plural and the adjective must agree with it (correct answer)
Explanation: When working with adjective agreement in Spanish, your first instinct should always be: what noun is this adjective actually describing? Identifying that noun — and only that noun — is the key to choosing the correct form. Here, Luisa wants to describe only los zapatos as new. Since zapatos is masculine and plural, the adjective must be masculine plural as well: nuevos. That makes D the correct answer. Spanish adjectives must match their noun in both gender (masculine/feminine) and number (singular/plural), so zapatos → nuevos is the natural, rule-following pairing. Choice A incorrectly suggests that adjective endings work as opposites of the noun's ending — there is no such rule in Spanish. The adjective mirrors the noun, it doesn't invert it. Choice B introduces a fictional rule about "mixed groups always taking the feminine plural." In reality, when a mixed-gender group shares one adjective, Spanish defaults to masculine plural — but more importantly, that rule doesn't apply here at all, since Luisa is only describing the shoes, not both items together. Choice C is a classic distraction: it points to chaqueta (feminine) as though proximity or sentence position gives one noun power over the adjective. But chaqueta is not being described as new — zapatos is, and that's the noun that controls agreement. A useful tip: before choosing an adjective form, underline the specific noun it modifies and check its gender and number independently. Don't let nearby nouns — especially feminine ones earlier in a sentence — pull your eye away from the noun actually being described.

Question 5

Which sentence correctly uses the adjective bueno (good) with a masculine singular noun?

  1. Es un buen hombre muy trabajador. (correct answer)
  2. Es un bueno hombre muy trabajador.
  3. Es un buena hombre muy trabajador.
  4. Es un buenos hombre muy trabajador.
Explanation: When you see a question about adjectives before masculine singular nouns in Spanish, you need to think about apocope — the shortening of certain adjectives when they appear directly before a noun. This is a key grammar rule that trips up many Spanish 1 students. The adjective bueno is one of several adjectives that drop their final -o when placed immediately before a masculine singular noun. So bueno becomes buen in that position. In choice A, buen hombre is exactly right — buen precedes the masculine singular noun hombre, following this shortening rule perfectly. The rest of the sentence (muy trabajador, meaning "very hardworking") is also grammatically correct. A is your answer. Choice B uses bueno in its full form directly before the noun, which violates the apocope rule. You can only use the full form bueno after the noun (e.g., el hombre es bueno) or standing alone. Choice C uses buena, which is the feminine form of the adjective — but hombre is masculine, so this is a gender agreement error. Choice D uses buenos, the masculine plural form, which mismatches the singular noun hombre in number. A helpful memory trick: think of the "BUENO brothers" — bueno, malo, primero, tercero, uno, alguno, ninguno — all masculine adjectives that lose their -o before a singular masculine noun. When you spot one of these adjectives directly in front of a masculine singular noun on your exam, always check that the -o has been dropped.

Question 6

A student wants to say 'They are good students' in Spanish, referring to a group of female students. Which sentence is correct?

  1. Ellas son buenas estudiantes. (correct answer)
  2. Ellas son buenos estudiantes.
  3. Ellas son buen estudiantes.
  4. Ellas son buena estudiantes.
Explanation: When you see a question like this in Spanish, you should immediately think about adjective agreement — the rule that adjectives must match the noun they describe in both gender (masculine/feminine) and number (singular/plural). Here, the subject is ellas (they, feminine), and the noun is estudiantes (students, plural). The adjective "good" must therefore be feminine AND plural, which gives you buenas. That makes option A — Ellas son buenas estudiantes — the correct sentence. The adjective buenas agrees perfectly with a feminine plural noun. Now let's look at why the other options fail. Option B uses buenos, which is the masculine plural form. Even though estudiantes can refer to males or females, the subject here is specifically ellas (feminine), so a masculine adjective is wrong. Option C uses buen, which is a shortened form of bueno used only before a singular masculine noun (e.g., un buen chico) — it cannot be used with a plural noun like estudiantes. Option D uses buena, which is feminine but singular, failing to match the plural noun. A helpful tip: whenever you see an adjective in Spanish, run a quick two-part check — (1) gender and (2) number). Ask yourself: is the noun masculine or feminine? Is it singular or plural? The adjective must match on both counts. A common trap is choosing the right gender but forgetting to make it plural (like option D does), so always double-check both features before selecting your answer.

Question 7

A student wants to say 'The problem is difficult' in Spanish. The noun problema is a masculine noun despite ending in -a. Which sentence is grammatically correct?

  1. El problema es difícila.
  2. El problema es difícil. (correct answer)
  3. La problema es difícil.
  4. El problema es difícilo.
Explanation: When working with adjectives in Spanish, you need to check two things: gender agreement and whether the adjective even has a gender-based ending. This question also tests a common vocabulary trap — nouns that end in -a but are actually masculine. Problema is one of several Spanish nouns (mostly borrowed from Greek) that end in -a yet are masculine. This means you must pair it with masculine articles and adjectives. The correct sentence is B) El problema es difícil — masculine article el, and the adjective difícil, which ends in -l and is a gender-neutral adjective that stays the same regardless of whether the noun is masculine or feminine. Here's why the other options fail: A) invents the form difícila — there is no such word. Difícil does not change its ending based on gender, so adding -a is simply a grammatical error. C) uses the feminine article la with problema, which contradicts its masculine gender — a classic trap for students who see the -a ending and assume femininity. D) invents difícilo, incorrectly adding a masculine -o ending to difícil. Again, this adjective has no masculine or feminine variant; it is invariable. A useful study tip: memorize a short list of masculine -a nouns — el problema, el programa, el sistema, el tema, el mapa — since they appear frequently on exams. Also remember that adjectives ending in -e or a consonant (like difícil, grande, fácil) are gender-neutral and never change their ending to match the noun's gender.

Question 8

Carlos describes a group: 'Tengo tres amigas francesas y un amigo  .'

Carlos wants to say his male friend is also 'French.' Which form of the adjective correctly fills the blank?

  1. francesas, to maintain consistency with the rest of the sentence
  2. francés, because it must agree with the masculine singular noun amigo (correct answer)
  3. franceses, because the whole group together is plural and masculine
  4. francesa, because French nationality adjectives are always feminine in Spanish
Explanation: When you see a question about adjectives in Spanish, your first instinct should be to identify the noun the adjective is describing — then match the adjective's gender and number to that specific noun. In this sentence, un amigo is masculine and singular. Spanish adjectives must agree with the noun they modify, so you need a masculine singular form of francés. That form is simply francés — making B the correct answer. The accent mark is part of the proper spelling for this masculine singular form, so don't drop it. The distractors each represent a different common mistake worth recognizing. A is tempting because students sometimes try to keep adjectives "consistent" across a sentence, but Spanish grammar doesn't work that way — each adjective agrees with its own noun independently. C would apply if you were describing the entire mixed group together (which would indeed use the masculine plural franceses), but Carlos is describing only un amigo here, not the group as a whole. D reflects a total misconception — nationality adjectives in Spanish are not fixed in any one gender. Francesa is the feminine singular form, which would be correct for a feminine noun like amiga, not for amigo. A useful memory trick: treat each noun-adjective pair as its own mini-agreement task. Ask yourself, "What is the gender and number of this specific noun?" then match accordingly. On Spanish-1 exams, adjective agreement questions often include nearby plural or feminine nouns as distractors designed to pull your attention away from the noun actually being modified.

Question 9

A student writes: 'Las clases son interesantes y el profesor es interesante también.' A classmate says this is wrong and that interesante should change form for the masculine noun. Who is correct, and why?

  1. The classmate is correct; interesante should be interesanto for masculine singular nouns.
  2. The classmate is correct; interesante should be interesantes to match the plural context of the sentence.
  3. The student is correct; interesante ends in -e and uses the same form for both masculine and feminine singular nouns. (correct answer)
  4. The student is correct; predicate adjectives after ser never change form for gender or number in Spanish.
Explanation: When working with adjective-noun agreement in Spanish, the first thing to ask yourself is: what letter does this adjective end in? That ending determines whether the adjective has separate masculine and feminine forms. Most adjectives ending in -o/-a follow the classic pattern — bonito/bonita, simpático/simpática — changing their ending to match the noun's gender. However, adjectives ending in -e (and most ending in consonants) are considered gender-neutral: they use the same form for both masculine and feminine nouns, only changing for number (singular vs. plural). Since interesante ends in -e, it stays interesante whether it modifies el profesor (masculine) or la clase (feminine). The student's original sentence is perfectly correct, making C the right answer. A is wrong because interesanto is not a real Spanish word. There is no rule that converts an -e adjective into an -o ending for masculine nouns — this reflects a common overgeneralization of the -o/-a pattern. B is wrong because interesantes is the plural form of the adjective, and el profesor es interesante is singular. While interesantes correctly modifies las clases earlier in the sentence, each adjective must match its own noun individually. D is wrong because predicate adjectives after ser absolutely do agree in both gender and number — él es alto, ella es alta, ellos son altos. The reason interesante doesn't change here is the -e ending rule, not its position in the sentence. Study tip: When you see an adjective ending in -e (like interesante, inteligente, importante), remember: same form, both genders — only add -s for plural.
