"If I Were A Rich Man"
Is this correct grammar?
Shouldn't Tevye be saying "If I was a rich man?"
"I was" is correct when referring to a fact or a real situation: "If I was awake I would have watched the game"
But when talking about an impossible situation, such as Tevye being a rich man, it is correct to use "if I were." The use of the plural form "were" instead of the usually correct singular "was" is like a signpost telling the reader (or listener) that the situation described in the sentence is unrealistic.
