Adjectives
Adjectives typically follow the nouns they modify, using the izāfa construct. However, adjectives can precede nouns in compounded derivational forms, such as khosh-bækht (lit. good-luck) 'lucky', and bæd-kār (lit. bad-deed) 'wicked'. Comparative forms ("more ...") make use of the suffix tær (تَر), while the superlative form ("the most ...") uses the suffix tærin (تَرین).
Comparatives used attributively follow the nouns they modify, while superlatives precede their nouns.
With respect to comparison, "than" is expressed by the preposition "از" (az), for example:
- سگ من از گربهی تو کوچکتراست
- (Sag-e man az gorbe to kuchektar ast; My dog is smaller than your cat.)
