617 well
1 well and good
Well and good can have similar meanings, but in this case well is an adverb, while good is an adjective. Compare:
- The car runs well (adverb modifying runs) (NOT The edr runs g88ti.)
It's a well-made car. (adverb modifying made)
It's a good car. (adjective modifying car)
- He teaches very well
I like that teacher. He's good. (NOT He's well)
- She speaks English well. (NOT She speaks Engli:sl1 g68ti.)
She speaks good English.
Her English is good.
Note that we cannot say She speaks weU English. (Adverbs cannot usually go between the verb and the object - see 21.1.)
2 well ='in good health'
There is also an adjective well, meaning 'in good health'. How are you?- Quite well, thanks.
I don't feel very well
Note that the adjective well is only used to talk about health. Compare: When I'm in the mountains I am always well.
When I'm with you I'm happy. (NOT Vlhetl :'fll with J'81t I'm weU.)
Well is not common before a noun. We can say She's well, but it is less usual to say, for example, She's a well girl.
For ill and sick, see 266. For well as a discourse marker, see 157.16,17,20.
618 when and if
A person who says when (referring to the future) is sure that something will happen. A person who says ifis unsure whether it will happen. Compare:
- I'll see you at Christmas when we're all at Sally's place.
(We are certain to be at Sally's place.)
I'll see you in August ifI come to New York. (Perhaps I'll come to New York, perhaps not.)
To talk about repeated, predictable situations and events (in the sense of 'whenever'), both when and ifcan be used with little difference of meaning.
Whenllfyou heat ice it turns to water.
WhenlIf I'm in Liverpool I usually stay with my sister.
