Hooking with -OLOGY words

Endings like -OLOGY 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.

This list by the numbers

The shape of this list: 265 entries between 6 and 15 letters long, peaking at 10 letters with 58 words. Five-letter picks number 0 and seven-letter picks 12. Nothing here outscores PSYCHOPATHOLOGY — 34 points from 15 tiles on plain squares.

ETHNOMUSICOLOGY (15 letters) stretches furthest, while the list-wide average score sits near 19 points.

Three easy picks from this list

OOLOGY earns 10 points from just 6 tiles — and it is a word few opponents will bother to challenge.
NEURORADIOLOGY — 14 letters for 19 points; every tile in it is a common draw, so it shows up rack after rack.
Playing NARRATOLOGY across a double-word square turns its base 15 points into 30 — solid value for 11 tiles.

Five more everyday options from the same list: NEONATOLOGY (15), SOTERIOLOGY (15), ROENTGENOLOGY (18), SELENOLOGY (14), STEREOLOGY (14).

Why -OLOGY endings win turns

A reliable habit: every time you learn a new -OLOGY 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.
