Comparative vs. Superlative Adjectives – English Grammar Exercises for A2

1  (A) nicer

• Why it’s right: “Nice” is a short adjective. To compare two dresses (red and blue), we add “-r”.
• Error Analysis: (B) is a Common Mistake (using “more” with a short adjective). (D) is a Structural Error (using the base adjective before “than”). (C) is a Strong Distractor (superlative is wrong because we are only comparing two items).

2  (A) more expensive

• Why it’s right: “Expensive” is a long adjective (3 syllables). To compare two things, we use “more + adjective”.
• Error Analysis: (B) is a Structural Error (adding “-er” to a long adjective). (D) is a Common Mistake (missing “more”). (C) is a Strong Distractor (superlative used instead of comparative).

3  (B) worse

• Why it’s right: “Bad” is an irregular adjective. The comparative form is “worse” (comparing blue and red).
• Error Analysis: (C) is a Common Mistake (applying regular rules “more bad”). (D) is a Structural Error (“bader” does not exist). (A) is a Strong Distractor (superlative used before “than”).

4  (D) the most beautiful

• Why it’s right: Comparing one dress to all the dresses seen today requires the superlative form of the long adjective “beautiful”.
• Error Analysis: (A) is a Common Mistake (missing the article “the”). (B) is a Structural Error (adding “-est” to a long adjective). (C) is a Strong Distractor (comparative used where superlative is needed).

5  (C) better

• Why it’s right: “Good” is an irregular adjective. Comparing the black dress to the red dress requires the comparative form “better”.
• Error Analysis: (B) is a Common Mistake (“more good”). (D) is a Structural Error (“gooder”). (A) is a Strong Distractor (superlative used for a 1-to-1 comparison).

6  (A) longer

• Why it’s right: “Long” is a short adjective. We add “-er” to compare the black dress and the red dress.
• Error Analysis: (B) is a Common Mistake (“more long”). (C) is a Structural Error (spelling mistake, adding an extra ‘g’). (D) is a Strong Distractor (superlative used before “than”).

7  (D) the most elegant

• Why it’s right: “Out of all three dresses” signals a comparison of three things, requiring the superlative form of the long adjective “elegant”.
• Error Analysis: (B) is a Common Mistake (missing “the”). (C) is a Structural Error (adding “-est” to a long adjective). (A) is a Strong Distractor (comparative form used for a group of three).

8  (A) heavier

• Why it’s right: “Heavy” ends in “y”. We drop the “y” and add “-ier” to compare the two dresses.
• Error Analysis: (C) is a Common Mistake (using “more” with a “y” ending adjective). (D) is a Structural Error (failing to change the “y” to “i”). (B) is a Strong Distractor (superlative used before “than”).

9  (C) the thinnest

• Why it’s right: Comparing one look out of all three requires the superlative. “Thin” is a CVC (Consonant-Vowel-Consonant) word, so we double the final “n”.
• Error Analysis: (B) is a Common Mistake (missing “the”). (D) is a Structural Error (forgot to double the “n”). (A) is a Strong Distractor (comparative used instead of superlative).

10  (C) softer

• Why it’s right: “Soft” is a short adjective. We add “-er” to compare the fabrics of the two dresses.
• Error Analysis: (A) is a Common Mistake (“more soft”). (D) is a Structural Error (missing the comparative form entirely before “than”). (B) is a Strong Distractor (superlative used before “than”).

11  (B) the most comfortable

• Why it’s right: Pointing out the peak level of comfort in the “whole shop” requires the superlative of a long adjective.
• Error Analysis: (C) is a Common Mistake (missing “the”). (D) is a Structural Error (adding “-est” to a long adjective). (A) is a Strong Distractor (comparative used instead of superlative).

12  (D) not as pretty

• Why it’s right: To say two things are unequal, we use the structure “not as + base adjective + as”.
• Error Analysis: (A) is a Common Mistake (putting a comparative adjective inside the “as…as” structure). (C) is a Structural Error (using “no” instead of “not”). (B) is a Strong Distractor (does not fit the grammatical structure).

13  (B) pricier

• Why it’s right: “Pricy” ends in “y”. We change “y” to “i” and add “-er” to compare the two prices.
• Error Analysis: (A) is a Common Mistake (“more pricy”). (D) is a Structural Error (keeping the “y”). (C) is a Strong Distractor (superlative used before “than”).

14  (B) the worst

• Why it’s right: Singling out the blue dress as the absolute bad choice among all options requires the superlative of “bad”.
• Error Analysis: (A) is a Common Mistake (missing “the”). (C) is a Structural Error (“the baddest” does not exist). (D) is a Strong Distractor (comparative used instead of superlative).

15  (C) nicer

• Why it’s right: “Nice” takes “-r” to compare two things. The modifier “much” correctly emphasizes the comparative.
• Error Analysis: (B) is a Common Mistake (“more nice”). (D) is a Structural Error (using “very” to modify a comparative, and adding a double comparative suffix). (A) is a Strong Distractor (superlative used before “than”).

16  (D) happier

• Why it’s right: “Happy” ends in “y”, so it becomes “happier” to compare how she looks now versus the other dresses.
• Error Analysis: (C) is a Common Mistake (“more happy”). (B) is a Structural Error (failing to drop the “y”). (A) is a Strong Distractor (superlative used before “than”).

17  (C) the easiest

• Why it’s right: Identifying the single best decision out of all possible decisions requires the superlative of “easy” (drop “y”, add “-iest”).
• Error Analysis: (A) is a Common Mistake (missing “the”). (D) is a Structural Error (using “most” with a “y” ending word). (B) is a Strong Distractor (comparative used where superlative is needed).

18  (A) the best

• Why it’s right: The absolute top choice out of “all the options” requires the superlative of “good” (“the best”).
• Error Analysis: (B) is a Common Mistake (missing “the”). (D) is a Structural Error (“the most good”). (C) is a Strong Distractor (comparative used instead of superlative).

19  (B) more stunning

• Why it’s right: “Stunning” is a long adjective. Comparing the black dress to “any other dress” directly uses the comparative “more stunning + than”.
• Error Analysis: (D) is a Common Mistake (using “most” before “than”). (C) is a Structural Error (adding “-er” to a long adjective). (A) is a Strong Distractor (superlative used before “than”).

20  (D) the prettiest

• Why it’s right: Declaring her the top beauty at the party requires the superlative form of “pretty”.
• Error Analysis: (A) is a Common Mistake (missing “the”). (C) is a Structural Error (using “most” with a “y” ending adjective). (B) is a Strong Distractor (comparative used instead of superlative).

1. Comparatives:
• Use when comparing TWO dresses (e.g., Red vs. Blue).
• Indicator word: Always look for “than”.
• Short adjectives: Add -er (nice → nicer, long → longer).
• Long adjectives: Add more (expensive → more expensive).
2. Superlatives:
• Use when comparing THREE OR MORE dresses to find the “ultimate” one (e.g., The black dress is the winner of all).
• Short adjectives: Add the + -est (thin → the thinnest).
• Long adjectives: Add the most (beautiful → the most beautiful).
• Golden Rule: You MUST include the article “the”.
3. Spelling Rules to Remember:
• Words ending in -y: Drop the ‘y’ and add -ier / -iest (heavy → heavier, pretty → the prettiest).
• CVC words (Consonant-Vowel-Consonant): Double the final consonant (thin → the thinnest).
4. Irregular Adjectives (Must Memorize):
• Good → Better → The best
• Bad → Worse → The worst
5. Advanced A2 Structures:
• Equality/Inequality: Use not as + base adjective + as (e.g., not as pretty as). Do not put comparative words like “prettier” inside this structure!
• Emphasis: Emphasize comparatives using words like “much” (e.g., much nicer). Never use “very” with comparatives (very nicer is incorrect).
