"Unfortunately that's wrong"

ALASNO

This phrase might follow a mistaken guess in a game show, combining a sigh of disappointment with a firm denial. Think of a two-word response where the first part is an old-fashioned exclamation.

The clue plays on the phrase "alas, no," which is a dramatic way to say "unfortunately, that's wrong." The answer takes the literal words "alas" and "no" and smashes them together without a comma or space. It’s a straightforward charade-style clue where the two parts combine to form the answer.
