Superlative Adjectives Quiz (Level A2-B1) - Grammar Practice

'the hardest' is correct because one-syllable adjectives form the superlative with -est, and 'the' must precede the superlative. 'the most hard' incorrectly uses 'most' with a one-syllable adjective, 'the harder' is a comparative form, and 'the hardest more' is not a valid superlative structure.

False because adjectives with three or more syllables form the superlative by using 'most' or 'least' before the adjective (e.g., 'most expensive', 'least interesting'). The -est suffix is used only with one-syllable adjectives and some two-syllable adjectives.

Superlative adjectives are used when comparing three or more items and expressing the highest or lowest degree of a quality. Comparatives are used only when comparing exactly two items.

The correct order is 'This is the smallest room in the house' because the superlative 'the smallest' (one-syllable adjective + -est) must follow the linking verb 'is', and the location phrase 'in the house' follows the noun.

'She is the most intelligent student in the class' is correct because adjectives with three or more syllables form the superlative with 'most'. 'She is the intelligenter student' uses the wrong comparative ending, 'She is the intelligentest student' incorrectly adds -est to a long adjective, and 'She is most intelligently student' misuses an adverb form.

'the most popular' is correct because 'popular' is a three-syllable adjective and requires 'most' to form the superlative, and 'the' must precede the superlative form in this context. 'the popularest' incorrectly adds -est to a long adjective, 'most popularer' mixes superlative and comparative forms, and 'the more popular' is a comparative, not a superlative.

'This is the newest phone in the shop' correctly uses the superlative 'the newest' to express the extreme degree among all phones in the shop. The other options use comparative forms ('newer than', 'more new than', 'newer of') which compare only two items rather than expressing the highest degree among three or more.

The correct order is 'Today was the happiest day of my life' because 'happiest' is formed by changing -y to -i and adding -est, it must be preceded by 'the', and the phrase 'of my life' follows the noun to show the group being compared.

'worst' is correct because 'bad' is an irregular adjective whose superlative form is 'worst' — it does not follow the standard -est or 'most' rules. 'baddest' incorrectly applies the regular -est rule, 'most bad' incorrectly uses 'most' with this irregular adjective, and 'most worst' doubles the superlative marker.

The sentence is incorrect because 'hot' is a one-syllable adjective and must form its superlative with -est (the hottest), not with 'most'. Additionally, when a one-syllable adjective ends in consonant-vowel-consonant, the final consonant is doubled before adding -est.

'the longest' is correct because 'long' is a one-syllable adjective that forms its superlative by adding -est, and the sentence requires the superlative form with 'the' to express the highest degree. 'the most long' incorrectly uses 'most' with a one-syllable adjective, 'the longer' is a comparative form, and 'the most longest' doubles the superlative marker.

Superlative adjectives are formed differently depending on the number of syllables and the adjective type: one-syllable adjectives take -est, two-syllable adjectives ending in -y change to -iest, adjectives with three or more syllables use 'most', and irregular adjectives have unique forms.

False because two-syllable adjectives ending in -y form the superlative by changing the -y to -i and adding -est (e.g., happy → happiest, crazy → craziest). Using 'most' before these adjectives is incorrect.

'This city has the least crime of any city in the country' correctly uses 'the least' as the superlative of 'little' to express the lowest degree among all cities. The other options either use comparatives, incorrectly form the superlative, or change the intended meaning.
