Why OI words matter

Words containing OI 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

The shape of this list: 2167 entries between 3 and 15 letters long, peaking at 8 letters with 446 words. Five-letter picks number 80 and seven-letter picks 329. Nothing here outscores HYPERTHYROIDISM — 32 points from 15 tiles on plain squares.

Chasing points? The best five entries here are HYPERTHYROIDISM (32), HYPOTHYROIDISMS (32), HYPOTHYROIDISM (31), EXPLOITATIVELY (29), PHOTOIONIZATION (29). The longest entry is ALLOTETRAPLOIDS at 15 letters, and the average word here is worth about 14 points. Letter-wise, I is the workhorse — it appears in 2167 of these words, ahead of O (2167) and E (1224).

Three words worth learning first

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

Round out your set with NOIL (4), NOIR (4), OILS (4), ROIL (4), SOIL (4) — all built from common tiles.

Learning words through OI

Groups like this one reward a different kind of practice: pick five words of different lengths from the list above, write each in a sentence, and the OI pattern moves into long-term memory. It is also a quiet Scrabble edge — racks that spell OI plus common tiles come up constantly, and prepared players cash them in while others shuffle letters.
