The adjective is a word expressing a quality of a substance.

The adjective has the following morphological characteristics:

Degrees of Comparison

Most adjectives have degrees of comparison: the comparative degree and the superlative degree.

NOTE: Some adjectives have no degrees of comparison.  

The comparative degree denotes a higher degree of quality. She is taller than her sister.

My box is smaller than hers.

The superlative degree denotes the highest degree of quality.

She is the tallest of the three sisters.

Her box is the smallest of all our boxes.

The noun modified by an adjective in the superlative degree has the definite article because the superlative degree of the adjective always implies limitation.

Adjectives form their degrees of comparison in the following way:

  • by the inflexion – er, – est (synthetical way);
  • by placing more and most before the adjective (analytical way).

Monosyllabic adjectives usually form their comparatives and superlatives in the first way, and polysyllabic adjectives in a second way.

The  following polysyllabic adjectives, however, generally form their comparative and superlative degrees inflexionally:

1. Adjectives of two syllables that end in – y, – ow, -er, and – le.

happyhappier(the) happiest
narrownarrower(the) narrowest
clevercleverer(the) cleverest
simplesimpler(the) simplest

2. Adjectives of two syllables that have the stress on the last syllable:

completecompleter(the) completest
conciseconciser(the) concisest

Some adjectives have irregular forms of degrees of comparison, e. g.:

goodbetterbest
badworseworst
many/muchmoremost
littlelessleast
farfarther/furtherfarthest/furthest
oldolder/elderoldest/eldest

Spelling rules

If the adjective ends in a consonant preceded by a stressed short vowel the consonant is doubled before – er, – est.

sadsadder(the) saddest
bigbigger(the) biggest

If the adjective ends in – y preceded by a consonant, у is changed into I before – er and – est.

busybusier(the) busiest
happyhappier(the) happiest

If the adjective ends in –e the e is dropped before –er and –est.

bravebraver(the) bravest
tinefiner(the) finest
