LUMEN as a word-puzzle answer

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

It leans on high-frequency letters (E, 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.

LUMEN by the numbers

Across the 1,734 curated answers in the Wordocious bank, E appears in 50% of answers (the 1st most common letter), L appears in 26% of answers (the 8th most common letter), N appears in 24% of answers (the 9th most common letter). 5 other answers share the opening “LU-”, so two green tiles up front still leave real guessing to do.

Difficulty: 1/5 — very approachable, because its letters are common and no close neighbors compete with it.
