A rounded or conical heap of stones erected by early inhabitants of the British Isles, apparently as a sepulchral monument.

CAIRN as a word-puzzle answer

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

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