Adjectives tell us something about a noun or pronoun.

Adjectives do not have a plural form. We use the same form for singular nouns (warm day), plural nouns (warm days, NOT warms days) and mass nouns (warm weather).

Many words are only adjectives, but sometimes we can make adjectives from

the -ing form of a verb: swimming pool

a past participle: tired boys

a noun: football stadium


Adverbs give extra information. They can tell us when (Unit 71), how often (Unit 73), how (Unit 80) and where (for example, Unit 79). They can also make a description stronger or weaker (Unit 67).

We can make many ADJECTIVES into ADVERBS with -ly. For example:

ADJECTIVE: bad, careful, slow, probable, happy
ADVERB: badly, carefully, slowly, probably, happily

These words are ADJECTIVES and also ADVERBS:

He is a hard worker.
He is a fast worker.
It's an early train.
She was late.

He works hard.
He works fast.
It arrives early.
She arrived late.

NOTICE: The adverbs hardly (Unit 67) and lately (Unit 71) have different meanings from hard and late.

This ADJECTIVE has an irregular form for its ADVERB:

He is a good worker.
He works well.

Some ADVERBS are ADVERBS only (there is no adjective). For example:

very (Unit 67) and almost (Unit 67).

NOTICE: Position of adjectives (Unit 65). Position of adverbs (Unit 66)
