Adjectives nearly always appear immediately before the noun or noun phrase that they modify.

This is unlike adverbs which can be placed almost anywhere within a sentence or phrase.  

Sometimes they appear in a string of adjectives, and when they do, they appear in a set order according to category - Order of Adjectives. When indefinite pronouns — such as something, someone, anybody — are modified by an adjective, the adjective comes after the pronoun:

Adjectives can express degrees of modification:

  • Maria is a rich woman, but Jose is richer than Maria, and Emily is the richest woman in town.

The degrees of comparison are known as the base, the comparative, and the superlative.

           comparative for comparing two things

           superlative for comparing three or more things.

The word than frequently accompanies the comparative and the word the precedes the superlative.

The suffixes -er and -est form most comparatives and superlatives, although -ier and -iest is used when a two-syllable adjective ends in y (happier and happiest).

We use more and most when an adjective has more than one syllable.

     Base – rich

     Comprarative- richer (1 syllable)

     Superlative - richest

    Base – dangerous

    Comprarative- more dangerous (3 syllables)

    Superlative - most dangerous

 

Certain adjectives have irregular forms in the comparative and superlative degrees:
