Classification of adjectives.
According to their meaning and grammatical characteristics adjectives fall under two classes: (1) qualitative adjectives, (2) relative adjectives.
1. Qualitative adjectives denote qualities of a substance directly, not through its relation to another substance, as size, shape, colour, physical and mental qualities, qualities of general estimation:
little, large, high, soft, hard, warm, white, blue, pink, strong, hold, beautiful, important, necessary, etc.
2. Relative adjectivesdenote qualities of a substance through their relation to materials (silken, woollen, wooden), to place (Italian, Asian), to time (monthly, weekly), to some action (preparatory, rotatory).
Grammatical characteristics of qualitative adjectives.
1.Most qualitative adjectives have degrees of comparison:
Some qualitative adjectives such as greenish, darkish, incurable, unsuitable, chief, principal, have no degrees of comparison.
2. They have certain typical suffixes, such as ‑ful, ‑less, ‑ous, ‑ent, ‑able, ‑y, ‑ish: careful, careless, dangerous, convenient, comfortable, silvery, watery, whitish, shortish.
3. From most of them adverbs can be formed by the suffix ‑ly:
graceful — gracefully
gay — gaily
4. Most qualitative adjectives can be used as attributes and predicatives.
