somewhere, anywhere follow the same rules as some and any; they are placed at the end of the sentence:
- I've talked to that woman somewhere.
- a) Can you see my hat anywhere?
b) No, I can't see it anywhere.
Sometimes we can place both the adverbs at the end of the sentence.
Are you going anywhere? (ordinary question) but
Are you going somewhere? (I assume that you are.)
Note: Nowhere is not normally placed at the end of the sentence. However, there's an exception to this rule: the expression "to get nowhere".
- What you're doing is getting you nowhere! (you'll get nothing by doing what you're doing)
Nowhere can be used for short answers:
- a) Where are you going?
b) Nowhere. (I'm not going anywhere.)
In formal English, these two adverbs of place can be put at the beginning of a sentence. They are then followed by an inverted verb like you can see below:
- Nowhere will you find a better candidate for this post.
