RENAL as a word-puzzle answer

RENAL is a 5-letter word with 2 vowels (E, A) and 3 consonants (R, N, L). Every letter is distinct, so it rarely punishes a clean opening guess.

It leans on high-frequency letters (R, E, N, A), 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.
