Comparative adjectives and adverbs are used to compare or contrast two people, things, or ideas and are usually separated by the word than.

If you want to form the comparative of an adjective or adverb, take the word and add -er to the end of it.

There are, of course, some exceptions. If the word ends in a -y, change the -y to -i and then add -er.

If an adjective or adverb is longer, usually with 2 or more syllables, leave the word as it is and just add the word "more" before it.

Examples:

dark: This shirt is darker than yours.

happy: I am happier today than I was yesterday.

difficult: Sherry thought that math was more difficult than science.

Position of Adjectives

Unlike Adverbs, which often seem capable of popping up almost anywhere in a sentence, adjectives nearly always appear immediately before the noun or noun phrase that they modify. Sometimes they appear in a string of adjectives, and when they do, they appear in a set order according to category. (See Below.) When indefinite pronouns — such as something, someone, anybody — are modified by an adjective, the adjective comes after the pronoun:

Anyone capable of doing something horrible to someone nice should be punished.
Something wicked this way comes.
