Adjectives
We use adjectives to describe nouns and pronouns. Adjectives can come before nouns or after linking verbs.
Before the noun:
- He dropped the hot plate.
- I have a black cat.
- The small boy ran down the street.
- What a beautiful view!
- He seems tired.
- The view is beautiful.
- The weather became cold.
- My cat is black.
We make the comparative and superlative of adjectives by adding either '-er / -est' or using 'more / most'. You can read more about comparatives and superlatives here.
- She is tall.
- She is taller than her sister.
- She is the tallest person in the class.
Adverbs are used to describe verbs, adjectives or other adverbs. They are often (but not always) made by adding 'ly' to the adjective.
- I walked slowly ('slowly' tells us about the verb 'walk').
- They worked quickly.
- She sang loudly.
- She sang more loudly than her friend.
- She sang most loudly in the class.
It's important to remember to use an adjective after a linking verb. However, this can be tricky as some verbs can be used as both normal verbs and as linking verbs. One test is to replace the verb with the same form of 'be' and see if the sentence still makes sense. If it does, the verb is being used as a linking verb and so needs an adjective, not an adverb.
- He smells the hot soup carefully. (Here we are talking about the action of smelling and using 'smell' as a normal verb, so we need an adverb.)
- The soup smells good. (Here we are using 'smell' as a linking verb, to describe the soup. We can replace 'smells' with 'is' and the sentence still makes sense. So, we need an adjective.)
- He looked tiredly at the dirty kitchen. (Here we are talking about the action of looking and using 'look' as a normal verb, so we use an adverb to describe the way of looking.)
- You look beautiful. (Here we are using 'look' as a nking verb, to give more information about the person. We can replace 'look' with 'are' and the sentence still makes sense. So we need an adjective.)
Normally, we make an adverb by adding 'ly' to an adjective.
- Careful (adjective): He is always careful.
- Carefully (adverb): She put the glasses down carefully.
- Quiet (adjective): This is a quiet room.
- Quietly (adverb): She spoke quietly.
- Bad (adjective): This coffee is bad!
- Badly (adverb): He sings badly!
- Happy (adjective): She looks very happy.
- Happily (adverb): He sang happily.
- Gentle (adjective): It's a gentle cat.
- Gently (adverb): He stroked the cat gently.
- Fast (adjective): That's a fast car.
- Fast (adverb): She walks fast.
- Early (adjective): She was early for the meeting.
- Early (adverb): He arrived early.
- Late (adjective): He is always late!
- Late (adverb): He got up late this morning ('lately' is also an adverb but means 'recently').
- Good (adjective): That is a good book.
- Well (adverb): She did well on the exam ('well' can also be an adjective; see below).
- Hard (adjective): Maths is hard!
- Hard (adverb): She tried hard ('hardly' is also an adverb, but means 'almost none'; see below).
- He talked to me in a friendly way.
'Well' can be confusing because it is both the adverb form of 'good', and an adjective that means 'healthy and fine'.
- My mother is well ('well' is an adjective that means 'healthy and fine').
- He did the work well ('well' is an adverb meaning 'in a good way').
- This meal is good!
- He can speak good German.
'Hard' is both an adjective and an adverb.
- The table is hard (= adjective, meaning 'not soft' or 'difficult').
- She works hard (= adverb, meaning 'with a lot of effort').
- She hardly works (= she does almost no work).
- I have hardly any money (= I have almost no money).
'Late' is an adjective and an adverb. There is also an adverb 'lately', which means 'recently'.
- I'm late (= adjective, meaning 'not on time').
- He came late (= adverb, meaning 'not on time').
- I've been working a lot lately (= an adverb meaning 'recently').
Many native English speakers are starting to use adjectives where traditionally we need an adverb. Some people think this is incorrect, but it's very common.
- He ran quick (instead of 'he ran quickly').
- She ran quicker (instead of 'she ran more quickly').
