Why RO words matter

Words containing RO are handy for Scrabble, Words with Friends and word puzzles — filter the list above by length to find the play you need.

This list by the numbers

The shape of this list: 10720 entries between 3 and 15 letters long, peaking at 9 letters with 1526 words. Five-letter picks number 273 and seven-letter picks 982. Nothing here outscores HYDROXYZINES — 38 points from 12 tiles on plain squares.

Chasing points? The best five entries here are HYDROXYZINES (38), HYDROXYZINE (37), EXOERYTHROCYTIC (35), HEXACHLOROPHENE (35), MICROEARTHQUAKE (35). ACHONDROPLASIAS (15 letters) stretches furthest, while the list-wide average score sits near 16 points. Letter-wise, O is the workhorse — it appears in 10720 of these words, ahead of R (10720) and E (6807).

Start with these three

ROE — 3 letters for 3 points; every tile in it is a common draw, so it shows up rack after rack.
ROT is easy to keep in memory: 3 letters, 3 points, and no awkward tiles to hunt for.
When the rack looks hopeless, AERO (4 letters, 4 points) is the kind of quiet play that keeps a game moving.

Once those stick, file away the next tier too: EROS (4), EURO (4), INRO (4), IRON (4), ROAN (4).

Learning words through RO

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