What are the main adjectives in English?

The main adjectives in English describe qualities, quantities, or characteristics of nouns. They can be categorized into several types, including descriptive adjectives (e.g., "happy," "blue"), quantitative adjectives (e.g., "some," "many"), demonstrative adjectives (e.g., "this," "those"), and possessive adjectives (e.g., "my," "your"). Adjectives typically precede the nouns they modify and can also follow linking verbs. Their function is to provide more information and detail about the nouns in a sentence.
