Playing words that start with OP

Leading with OP lets you hook onto open columns and reach premium squares. Scan the high-scoring entries above first — they offer the best return when you have the tiles.

This list by the numbers

The shape of this list: 320 entries between 2 and 15 letters long, peaking at 9 letters with 56 words. Five-letter picks number 10 and seven-letter picks 37. Nothing here outscores OPHTHALMOSCOPIC — 31 points from 15 tiles on plain squares.

Chasing points? The best five entries here are OPHTHALMOSCOPIC (31), OPHTHALMOSCOPY (31), OPHTHALMOSCOPES (29), OPHTHALMOSCOPE (28), OPHTHALMOLOGIC (27). OPENHEARTEDNESS (15 letters) stretches furthest, while the list-wide average score sits near 15 points. If you are fishing for these words, keep P (320 appearances), O (320) and E (209) on your rack.

Start with these three

OPENER — a 6-letter, 8-point play that slots into tight board lanes where longer words won't fit.
OPERAS — 6 letters for 8 points; every tile in it is a common draw, so it shows up rack after rack.
Playing OPERON 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: OPIATE (8), OPINES (8), OPSINS (8), OPTION (8), OPUSES (8).

Learning words through OP

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 OP pattern moves into long-term memory. It is also a quiet Scrabble edge — racks that spell OP plus common tiles come up constantly, and prepared players cash them in while others shuffle letters.
