- 1. Because, as, since, for, inasmuch as agree in implying a reason for an occurrence or action. Because introduces a direct reason:I was sleeping because I was tired.As and since are so casual as to imply merely circumstances attendant on the main statement:As(or since) I was tired, I was sleeping. The reason, proof, or justification introduced by for is like an afterthought or a parenthetical statement:I was sleeping, for I was tired.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.
- 1. See reason.
