my wife and i
It is correct if it is what you intend to say. If you mean that your friend heard something, and then related it to you, you can say that it was heard by a friend. Your friend heard it. If you mean that YOU heard something, and you heard it because your friend told you, then you heard it from a friend.
My wife and I are on the phone
you correct them.
"Between him and his wife" is correct. You wouldn't say "It's between they". You would say "It's between them". So the objective pronoun (him) is correct and not the subjective pronoun (he).
Your friend lives on Broad Street is the correct form.You would say: Your friend lives in Albany.You would say: Your friend lives at the corner of Broad Street and River Road.
No. Him and me is correct.
"Former friend of Jane and me" is grammatically correct. In this case, "me" is the correct pronoun to use since it is the object of the preposition "of."
It's correct to say that a person is good AT mathematics.
god venn = good friend
You would say "Ẹ ku ọsan ti ti dà" in Yoruba to mean "Good morning, my wife."
It all depends on how you use it. to determine if one should use I or me, they need only take off the _____ and part of the sentence. For example, you would say "My wife and I are going out" If you took off "my wife and" then you can see the correct grammar is there (I am going out). However, if you said My wife and me are going to the store, once again take off "my wife and" and you have Me am/are giong to the store. Incorrect! :)
Mera bahut achha dost. That is how you say good friend in Hindi.
