Hooking with -SION words

Endings like -SION 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

The shape of this list: 255 entries between 6 and 15 letters long, peaking at 10 letters with 54 words. Five-letter picks number 0 and seven-letter picks 18. Nothing here outscores HYPEREXTENSION — 29 points from 14 tiles on plain squares.

The five biggest scorers on the page: HYPEREXTENSION (29), IMMUNODIFFUSION (26), OVEREXPANSION (25), INCOMPREHENSION (24), MISAPPREHENSION (24). At 15 letters, AUTOTRANSFUSION is the longest word on the list; a typical entry scores around 14. Letter-wise, S is the workhorse — it appears in 255 of these words, ahead of N (255) and I (255).

Start with these three

When the rack looks hopeless, LESION (6 letters, 6 points) is the kind of quiet play that keeps a game moving.
NASION earns 6 points from just 6 tiles — and it is a word few opponents will bother to challenge.
Playing BASION across a double-word square turns its base 8 points into 16 — solid value for 6 tiles.

Once those stick, file away the next tier too: FUSION (9), VISION (9), ELISION (7), ELUSION (7), ERASION (7).

-SION as a board weapon

When the board tightens up late in a Scrabble game, -SION words keep you scoring: they attach to existing letters instead of needing seven clean tiles. Crossword solvers use the same trick in reverse — if the grid gives you the last letters, this list is the candidate pool. Check the length filter in the Word Finder to match your open squares exactly.
