as if and as though; like
Meaning
As if and as though are both used to say what a situation seems like. They can refer to something that we think may be true.
- It looks as if/though it’s going to rain.
- It sounds as if/though Jack’s going to change his job.
They can also be used to talk about things which we know are not true.
- I feel as if/though I’m dying.
- She was acting as if/though she was in charge.
Tenses
When we talk about things which we know are not true, we can use a past tense with a present meaning after as if/though. This emphasises the meaning of unreality. Compare:
- She looks as if she is rich. (Perhaps she is.)
He talks as if he was rich. (But he is definitely not.) - You look as though you know each other.
Why is he looking at me as though he knew me? I’ve never seen him before.
In a formal style, were can be used instead of was in an ‘unreal’ comparison. This is common in American English.
- He talks as if he were rich.
like meaning ‘as if/though’
Like is often used in the same way as as if/though, especially in an informal style. This used to be typically American English, but it is now common in British English.
- It seems like it’s going to rain.
- He sat there smiling like it was his birthday.
