High-Scoring Two-Letter Scrabble Words You Need to Memorize
Ask any tournament Scrabble player which words separate beginners from intermediates and you’ll get the same answer: the two-letter list. They look like nothing — QI, ZA, JO, KA — but the points they unlock through parallel plays can swing entire games. Here’s what to memorise and why.
Why two-letter words matter
A two-letter word on its own scores almost nothing — usually 2 to 4 points. But that’s not why they matter. The real value is in parallel plays: dropping a word alongside an existing word on the board so both the new word AND every two-letter word formed where the new word touches the old one all score together. One play, multiple scoring lanes.
Without the two-letter list, you can only play perpendicular to existing words at single hook points. With it, you can lay a 5-letter word alongside an existing 5-letter word and score six different ways at once. This is how 40-point plays become 80-point plays.
The high-scoring two-letter words (and why)
All scores assume no premium squares. With premium-square placement, double or triple these numbers.
| Word | Score | Meaning | Valid in |
|---|---|---|---|
| QI | 11 | Vital life force in Chinese philosophy | TWL & SOWPODS |
| ZA | 11 | Slang for pizza | TWL & SOWPODS |
| ZO | 11 | A Tibetan animal, hybrid of yak and cow | SOWPODS only |
| JO | 9 | A sweetheart (Scottish) | TWL & SOWPODS |
| XI | 9 | The fourteenth letter of the Greek alphabet | TWL & SOWPODS |
| XU | 9 | A Vietnamese monetary unit | TWL & SOWPODS |
| AX | 9 | Variant spelling of axe | TWL & SOWPODS |
| EX | 9 | The letter X; a former partner | TWL & SOWPODS |
| OX | 9 | A castrated bull used for work | TWL & SOWPODS |

| KI | 6 | Vital energy in Japanese philosophy | TWL & SOWPODS |
| WO | 5 | Archaic variant of woe | TWL & SOWPODS |
The unusual ones (low score but lifesavers)
These won’t score huge on their own, but they unlock parallel plays in racks where every other letter is wrong. Memorise them.

| EN | 2 | The letter N; half the width of an em |
| ES | 2 | The letter S |
| ET | 2 | Past tense of eat (dialect) |

| UN | 2 | One (dialect) |
| UT | 2 | The musical syllable for C (predecessor of do) |

If you didn’t know AA, OE, or NA were valid — you’re not alone. Most casual players don’t. Memorising these is the single biggest cheap upgrade you can give your game.
Words valid in WWF but NOT Scrabble
If you play both Words With Friends and Scrabble, watch for these — valid in WWF but rejected in TWL Scrabble:
- BAE — before anyone else (slang). Three letters, not two, but the same trap applies.
- OK — was a WWF-only word for years; TWL added it relatively recently. Still not accepted in some older Scrabble editions.
- EW — an expression of disgust. Modern; added to TWL after WWF.

Putting them to work: parallel play patterns
Knowing the words is half the battle. Knowing how to use them is the rest. The three most common high-leverage patterns:
1. The Q-dump
Opponent plays a word ending in I. You play parallel above it, ending your word with Q. The Q + I forms QI for 11 points on top of your main word’s score. A Q on a triple-letter square here can score 30+ from the parallel alone.
2. The Z-stack
Same principle, with ZA: opponent plays a word containing A in a tight spot. You play your word with the Z above the A. Result: ZA scores 11 (or 22 with a double letter on the Z) in addition to your main word.
3. The X-double
X is unique — it forms a valid two-letter word with five different letters: AX, EX, OX, XI, XU. This makes the X the most flexible high-value tile for parallel plays. Aim to place X on a double-letter square between two letters that both form valid X-words.
Practice routine to memorise the list
You don’t need to memorise all of them. Even the most studied tournament players use a tiered approach. Here’s a 10-minute daily drill that works:
- Day 1: learn the top 6 high-scorers: QI, ZA, JO, XI, AX, EX. Test recall an hour later.
- Day 2-3: add OX, XU, KA, KI, WO. Drill until automatic.
- Day 4-7: work through the "unusual" table above — AA, AE, BA, OE, NA, ES, ET, OD, OM, OP, OS, OY, UN, UT. Five new ones per day.
- After 1 week: open our Word Finder, set the length filter to 2, and scroll through. Words you can't define are your last gaps.
By week two, you’ll have around 80% of the tournament 2-letter list memorised. The remaining 20% are rare enough that you can pick them up by exposure during play.
The bottom line
Two-letter words are the single highest-leverage investment in Scrabble study. A casual player who memorises 30 two-letter words will out-score a stronger player who hasn’t — not because of the words’ own points, but because of the parallel-play opportunities they unlock. Start with the four big ones (QI, ZA, JO, KA), build from there, and your average score per game should jump 20-40 points within a month.
