Perhaps when you're asking about something that occurred the day before today. For example, you might ask, "What did you do yesterday?"
It is incorrect. You may use "You saw him yesterday" as a statement or "You saw him yesterday?", as a question
That question should be, did you speak to her yesterday.
This is how you use yesterday in a sentence I went to the carnival yesterday afternoon
What did you write yesterday is already past tense.The auxilary verb did shows us the question is past tense. Plus yesterday shows the question is past.
Depending of if it is a question or a statement: Did it rain yesterday? OR It rained yesterday.
Like this: I did my history homework yesterday. That's how you use yesterday as an adverb in a sentence
I went to my friend's house yesterday.
No, this is not correct. 'Yesterday' indicates past time but 'send' is the present tense of the verb. It is not idiomatic to use the perfect tense with 'yesterday'. The past tense should be used. Here are some possible constructions: Past tense: 'You sent [it] yesterday.' 'Did you send [it] yesterday?' Perfect tense: 'You have sent [it] already; there is no need to send it again.' 'Have you sent [it] yet?'
What a stupid question.
The correct phrase is "Whom did you meet yesterday?" because "whom" is used as the object of the verb "meet" in this question.
"That's yesterday's news..." uses 'yesterday' to qualify the pronoun 'news'.
No. You could say 'you could have come yesterday', or 'you would have come yesterday', or 'if you had come yesterday', though.
