Comparative Forms
In English, we use adjectives and adverbs to compare objects, places, and people with certain
rules depending on the type of adjective or adverb that is being used to make the comparison.
1. When we use one-syllable adjectives or adverbs to compare, “er” is added at the end of the adjective
or adverb followed by the word than. When the adjective ends in a consonant preceded by a single vowel, the
final consonant is duplicated.
2. When we make comparisons using two-syllable adjectives or adverbs that end in y, the y is changed into ier
followed by the word than.
3. When making a comparison using three-syllable adjectives or adverbs the word “more” precedes them. We also
have to add the word than after the adjective or adverb.
