POSER

Meaning

A particularly difficult question or puzzle.

POSER as a word-puzzle answer

POSER is a 5-letter word with 2 vowels (O, E) and 3 consonants (P, S, R). Every letter is distinct, so it rarely punishes a clean opening guess.

It leans on high-frequency letters (O, S, E, R), so a strong vowel-and-common-consonant opener tends to light up quickly. There are no rare letters here, so it is a fair, mid-difficulty answer for the daily Classic puzzle.
