Invite to one's loft, say

ASKUP

Think of a casual way to request someone join you in a higher place, like a treehouse or apartment. The answer is a common phrase split into two words.

This clue plays on the phrase "ask up," which can mean inviting someone upstairs—like to a loft. The word "say" hints that "loft" is just an example, not part of the answer. "ASKUP" combines "ask" (invite) and "up" (to a higher place), making it a clever split of the phrase. It’s a common crossword trick where a simple action gets broken into parts.
