A quick statistical tour

Inside this list: 1692 words spanning 3–15 letters. The biggest cluster sits at 8 letters (298 words), 49 entries are Wordle-sized at five letters, and 172 run to seven — bingo length if you can empty the rack. For points, the ceiling is TRANQUILLIZING, worth 33.

For quick reference, the top of the score table reads: TRANQUILLIZING (33), TRANQUILLIZED (32), TRANQUILLIZERS (32), TRANQUILLIZER (31), TRANQUILLIZES (31). BOUGAINVILLAEAS (15 letters) stretches furthest, while the list-wide average score sits near 14 points.

Three words worth learning first

ILL earns 3 points from just 3 tiles — and it is a word few opponents will bother to challenge.
ILLS — 4 letters for 4 points; every tile in it is a common draw, so it shows up rack after rack.
Playing NILL across a double-word square turns its base 4 points into 8 — solid value for 4 tiles.

Once those stick, file away the next tier too: RILL (4), SILL (4), TILL (4), ILLER (5), NILLS (5).

One chunk, many words: ILL

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