Adjectives.
    Adjectives are the third major class of words in English, after nouns and verbs. Adjectives are words expressing properties of objects (e.g. large, blue, simple, clever, economic, progressive, productive, etc) and, hence, qualifying nouns.
    Adjectives in English do not change for number or case. The only grammatical category they have is the degrees of comparison. They are also characterized by functions in the sentence. Degrees of Comparison.
    There are three degrees of comparison: positive, comparative and superlative. The positive form is the plain stem of an adjective (e.g. heavy, slow, straight, etc) . The comparative states that one thing has more of the quality named by the adjective than some other thing (e.g. Henry is taller than John). The superlative states that the thing has the greatest degree of the quality among the things being considered (e.g. Henry is the tallest boy in the class)
    Most one-syllable adjectives, and most two-syllable adjectives ending in -y, -ow, -er, or consonant +-le , with loud stress on the first syllable and weak stress on the second, form their comparative and superlative by the addition of the suffixes -er and -est. Positive Comparative Superlative clever cleverer cleverest narrow narrower narrowest pretty prettier prettiest simple simpler simplest Adjectives derived by prefixes from those that use -er/-est also use these suffixes, even though the addition of prefixes makes them longer that two syllables: unhappy - unhappier -unhappiest
    All adjectives other than those enumerated above form their comparative by using the intensifier more and their superlative by using the intensifier the most. Positive Comparative Superlative interesting more interesting the most interesting generous more generous the most generous personal more personal the most personal In a very few cases, English permits a choice between the two devices: commoner / more common, commonest / the most common. Ordinary, when one form is prescribed by the rules, the other is forbidden.
    A few adjectives have irregular forms for the degrees of comparison. They are:
    good - better - the best
    bad - worse - the worst
    far - farther - the farthest (for distance) - further - the furthest (for time and distance)
    near - nearer - the nearest (for distance) - next (for order)
    late - later - the latest (for time) - last (for order)
    old - older - the oldest (for age) - elder - the eldest (for seniority rather the age; used only attributively)
    There are some adjectives that, on account of their meaning, do not admit of comparison at all, e.g. perfect, unique, full, empty, square, round, wooden, daily, upper, major, outer, whole, only and some others.
    There are sentence patterns in which comparison is expressed: a) comparison of equality (as ... as) e.g. The boy was as shy as a monkey.
    After his bathe, the inspector was as fresh as a fish.
    When he had left Paris, it was as cold as in winter there. b) comparison of inequality (not so ... as, not as ... as) e.g. His skin was not so bronzed as a Tahiti native's.
    The sun is not so hot today as I thought it would be.
    You are not as nice as people think. c) comparison of superiority (... -er than, ... -est of (in, ever) e.g. He looked younger than his years, much younger than Sheila or me.
    To my mind the most interesting thing in art is the personality of the artist.
    My mother was the proudest of women, and she was vain, but in the end she had an eye for truth.
    It's the biggest risk I've ever had to take. d) comparison of inferiority ( less ... than) e.g. John is less musical than his sister.
    He had the consolation of noting that his friend was less sluggish than before. e) comparison of parallel increase or decrease (the ... the, ...-er as) e.g. The longer I think of his proposal the less I like it.
    The sooner this is done, the better.
    He became more cautious as he grew older.
    There are set phrases which contain the comparative or the superlative degree of an adjective: a) a change for the better (for the worst) - перемена к лучшему ( к худшему) e.g. There seem to be a change for the better in your uncle. He had a very hearty dinner yesterday. b) none the less - тем не менее e.g. It did not take him long to make up his mind. None the less she showed her scorn for his hesitation. c) so much the better ( the worst) - тем лучше (хуже) e.g. If he will help us, so much the better.
    If he doesn't work, so much the worst for him. d) to be the worst for - делать что-то хуже, еще больше e.g. He is rather the worst for drink. e) no (none the) worse for - хуже не станет (не стало) от ... e.g. You'll be no worse for having her to help you.
    You are none the worse for the experience. f) if the worst comes to the worst - в худшем случае e.g. If the worst comes to the worst, I can always go back home to my parents. g) to go from bad to worse - становиться все хуже и хуже e.g. Thinks went from bad to worse in the family. h) as best - в полную меру старания, как только можно e.g. ............
