Is it correct to say ian and you?

Answer 1

The phrase "Ian and you" is technically correct, but it has long been considered "impolite". For traditional politeness, "you" or "your" should be the first part of a compound element in a sentence, so that the hearer will understood that the speaker or writer appreciates the hearer's or reader's importance, and "I", "me", "my", or "mine" should be the last word in a compound element to avoid sounding conceited.
