Adjectives are generally invariable in English and do not agree with nouns in number and gender; nor do they take case endings:
However, a few adjectives have a connotation which is slightly masculine or feminine. Thus, one says that a woman is beautiful while a man would be called handsome.
Adjectives indicating religion or nationality (or a region, state or province) generally begin with a capital letter, whether they refer to people or objects:
In a noun cluster an adjective will be placed, with very few exceptions, in front of the noun it modifies. When two adjectives precede a noun, they can be connected by a comma (,) or by the conjunction "and". In a series of three or more adjectives, one usually uses "and" before the last adjective in the list.
An adjective may follow the noun when it is in a predicate (after the verb) or in a relative clause. (In relative clauses the relative pronoun may be implicit).
