Can the words "is" and "that" be used back-to-back in the following sentence?
The reason I went to the store is that I ran out of milk.
Similarly, can "is" and "because" be used as such? For example:
The reason I went to the store is because I ran out of milk.
X BethatS. A that complement clause (as here) can be used as the predicate of an identificational sentence withX(hereX= The reason (that/why) I went to the store) and the form ofBeis is. A because clause is also acceptable when theXis a reason or cause; this is the case here, but not everywhere. – John Lawler Oct 07 '14 at 02:05
