"Hmm, no idea"

IMATALOSS

This phrase might follow a shrug when someone admits they’re completely baffled or out of answers. Think of a casual way to say "I give up."

The clue plays on the phrase "I'm at a loss," which people often say when they don’t know something—just like "Hmm, no idea." The answer twists this into "IMATALOSS" by removing the spaces and "a" to make it fit a crossword’s single-word format. It’s a common crossword trick where a spoken phrase gets condensed into a solid string of letters.
