Adjectives are words used to tell us more about an object. We use adjectives when we want to tell more about a noun. Example: This is a small table. The word ”small” tells us something about the table. It is an adjective.
‘A’, ‘an’ and ‘the’ are used for any singular count nouns. We use ‘a’ before words that begin with a consonant sound and ‘an’ before words that begin with a vowel sound. ‘The’ is used when referring to a particular noun.
