Can you refer me to some resources for understanding conditionals?

Which one is right: "If I were..." or "If I was..."

Conditionals in English are important for indicating mood, politeness, and degrees of politeness. I will refer you to the experts. The websites below have nice explanations about the conditionals. For a more in-depth explanation, take a look at the Biber, Conrad, and Leech Student Grammar.

Do you know the song "If I were a rich man..."? The example "If I were" is a bit of a dying breed in English. You will here people use "If I was" in its place everywhere. The language is changing. However, "If I were..." attempts to indicate that the situation is entirely unreal and impossible. "If I were you, I would..." (I cannot be you, I am not you, and I cannot become you). The resources listed here have more, but that is the gist. "If I were" is technically more correct in this meaning, but "If I was" is widely used.

Which resources did you use to find the solution? Were the resources useful?
