Word Usage
the reason is that... or the reason is because...?

The word reason is correctly followed by that rather than by the redundant because in sentences of the type The reason I left is that [not because] I was bored. Alternatively, simply use: I left because I was bored. Informally, however, and especially in conversation, the reason is because does occur and that is sometimes omitted altogether: The reason I left is because I was bored. The reason I left is I was bored.
