The Alphabet Game has always required words that are tied to DS. Please submit answers with specific examples if their tie-in isn't obvious, which lately has not always been the case. If that isn't possible, then please leave it to someone else or perhaps allow the "game" to end. Thanks!
Since no example was provided in the answer given this morning other than that "it must have been mentioned at one time or another," another word is needed. So, next is A.
