Hooking with -ISM words

Endings like -ISM let you tack a word onto a tile already on the board, often turning a small play into a big one. Look for the high-value entries above to maximise points.

A quick statistical tour

A few numbers before you scroll: the 832 words here run from 4 to 15 letters, with 8-letter words the largest group (133 entries). Wordle players have 4 five-letter options, and there are 61 seven-letter candidates for a Scrabble bingo. The single best scorer is HYPERTHYROIDISM at 32 points before multipliers.

The five biggest scorers on the page: HYPERTHYROIDISM (32), HYPOTHYROIDISM (31), NONOBJECTIVISM (30), CRYPTORCHIDISM (29), HYPERCATABOLISM (29). ANTHROPOPATHISM (15 letters) stretches furthest, while the list-wide average score sits near 17 points. Letter-wise, M is the workhorse — it appears in 832 of these words, ahead of S (832) and I (832).

Start with these three

Playing AUTISM across a double-word square turns its base 8 points into 16 — solid value for 6 tiles.
EONISM earns 8 points from just 6 tiles — and it is a word few opponents will bother to challenge.
NANISM — 6 letters for 8 points; every tile in it is a common draw, so it shows up rack after rack.

Round out your set with TRUISM (8), SEISM (7), AGEISM (9), EGOISM (9), IODISM (9) — all built from common tiles.

Back-hooking with -ISM

A reliable habit: every time you learn a new -ISM word, note whether it also takes a front extension. Words that extend at both ends are the ones that turn a 12-point play into a 40-point one, because you can bridge two premium squares. The top of this list — sorted by score — is where those double-duty words hide.
