Till and by

AnonymousThe sentence #1 is correct?

Yes, but I see no call for the past perfect without further context; use 'raised' (simple past) alone.

Anonymousand #2 is incorrect?

Yes.

Thanks ,Mr.MM!
I understand

I have one more question.
Can I use "before" instead?

3)My grandmother had raised me before I was five years old.

That is a little hard to interpret. This would be clearer:

My grandmother had been raising me before I was five years old.

Thanks,Mr.MM
I was going to ask the passive voice of the sentence next.

1)I had been raised by my grandmother before I was five years old.
2) I had been being raised by my grandmother before I was five years old.

I have these two sentences in mind now.
grammatically correct but awkward?

Anonymousgrammatically correct but awkward?

Yes, especially #2.

Thanks again,Mr.MM

1)I had been raised by my grandmother before I was five years old.
2)I had been raised by my grandmo

Anonymousso,#2 is the most natural sentence?

Among the ones you have presented, yes, but I think it is wrong; as I said, this is the expected:

I was raised by my grandmother till I was five years old.

Thanks a lot for the help

I really understand well
