This lesson (again in the beginner course) explains enharmonics in terms of natural notes versus accidental notes:

We intentionally avoided the term enharmonic in that series of lessons, though. We did that to avoid using "big scary musical theory terms" in lessons for absolute beginners. :) Also, because it was just as accurate to use the term accidental and especially since we could contrast that term with natural.
