Usage

What are other ways to say since? The conjunctions as and since suggest a reason for an occurrence or action, but they are so casual as to imply merely circumstances attendant on the main statement: As (or since) I was tired, I was sleeping. Because introduces a direct reason: I was sleeping because I was tired. The reason, proof, or justification introduced by for is like an afterthought or a parenthetical statement: I was famished, for I had not eaten all day. The more formal inasmuch as implies concession; the main statement is true in view of the circumstances introduced by this conjunction: Inasmuch as I was tired, it seemed best to sleep.
