Why AU words matter

Words containing AU are handy for Scrabble, Words with Friends and word puzzles — filter the list above by length to find the play you need.

A quick statistical tour

A few numbers before you scroll: the 2120 words here run from 3 to 15 letters, with 9-letter words the largest group (340 entries). Wordle players have 104 five-letter options, and there are 258 seven-letter candidates for a Scrabble bingo. The single best scorer is CHEMOAUTOTROPHY at 30 points before multipliers.

The five biggest scorers on the page: CHEMOAUTOTROPHY (30), BUREAUCRATIZING (29), EXHAUSTIBILITY (29), BUREAUCRATIZED (28), EXHAUSTIVELY (28). ASTRONAUTICALLY (15 letters) stretches furthest, while the list-wide average score sits near 14 points. Letter-wise, A is the workhorse — it appears in 2120 of these words, ahead of U (2120) and E (1216).

Start with these three

When the rack looks hopeless, EAU (3 letters, 3 points) is the kind of quiet play that keeps a game moving.
SAU — a 3-letter, 3-point play that slots into tight board lanes where longer words won't fit.
TAU — 3 letters for 3 points; every tile in it is a common draw, so it shows up rack after rack.

Round out your set with AUNT (4), AURA (4), AUTO (4), LUAU (4), SAUL (4) — all built from common tiles.

AU as a vocabulary shortcut

If you are studying English, AU is a high-leverage chunk: instead of memorising each word cold, anchor the AU pattern and let the surrounding letters vary. Word-game players get a parallel benefit — when a crossword grid or a Wordle guess reveals the AU sequence, this page is the complete candidate pool, already sorted by Scrabble value.
