How to Memorize All Two-Letter Scrabble Words

There are 127 valid two-letter words in SOWPODS (the international Scrabble dictionary). That sounds like a lot, but you already know most of them. The challenge isn't learning 127 words from scratch — it's filling in the 40-50 unusual ones you don't naturally recognise. Here's how to do it efficiently using proven memory techniques.

Method 1: Vowel Grouping

The most popular technique among competitive players is grouping by starting vowel. This works because vowels are the connective tissue of parallel plays — when you place a word beside an existing one, the vowels in your word need to pair validly with adjacent consonants.

Here's how to break it down:

• ▶A-words (16): AA, AB, AD, AE, AG, AH, AI, AL, AM, AN, AR, AS, AT, AW, AX, AY — learn as a rhythm: "AA-BAD AE-GAH AI-LAMAN AR-AS-AT AW-AX-AY"
• ▶E-words (10): EA, ED, EE, EF, EH, EL, EM, EN, ER, ES — the "EE-EF" pair and "EL-EM-EN-ER-ES" sequence are naturally memorable
• ▶I-words (2): IF, IN — you already know both
• ▶O-words (16): OB, OD, OE, OF, OH, OI, OM, ON, OO, OP, OR, OS, OU, OW, OX, OY — the "OB-OD" pair and "OM-ON-OO-OP-OR-OS" run
• ▶U-words (8): UG, UH, UM, UN, UP, UR, US, UT — mostly common except UG, UR, and UT

Learn one vowel group per day. By the end of a week, you've covered all vowel-initial words. The remaining consonant-initial words are mostly everyday English (BE, BY, DO, GO, HE, etc.) with a few surprises.

Method 2: Mnemonic Sentences

Create memorable phrases where each word starts with the same letter as the two-letter words you're learning. For the tricky consonant groups:

• ▶K-words (KA, KI): "KA the KI" — imagine KA (a spiritual double in Egyptian mythology) and KI (life force energy in Japanese)
• ▶X-words (XI, XU): "XI and XU went to Greece and Vietnam" — XI is a Greek letter, XU is a Vietnamese monetary unit
• ▶Z-words (ZA, ZO): "ZA pizza with ZO" — ZA is slang for pizza, ZO is a Tibetan yak hybrid
• ▶Q-words (QI): "QI flows without U" — the only Q-without-U two-letter word, from Chinese philosophy

The sillier or more vivid the mnemonic, the better it sticks. Competitive players often share their favourite mnemonics in club settings — there's no single "correct" one.

Method 3: Flashcard Drilling

Physical or digital flashcards remain one of the most effective memorisation tools. Here's how to set them up for two-letter words:

• ▶Front: The two-letter combination (e.g., "QI")
• ▶Back: Valid/Invalid + brief definition + point value (e.g., "Valid — life force energy (Chinese) — 11 pts")
• ▶Include invalid combinations: Mix in fakes like QA, ZE, VU so you practice rejection as well as recognition

Digital apps like Anki or Quizlet work particularly well because they handle the scheduling automatically. Create a deck of all 127 valid words plus 30-40 invalid pairs, and review for 10 minutes daily.

Method 4: Spaced Repetition

Spaced repetition is the science-backed technique of reviewing material at increasing intervals. Instead of cramming all 127 words in one session, you review them on a schedule: day 1, day 3, day 7, day 14, day 30.

The principle is simple: words you get right move to longer intervals, words you miss get reviewed sooner. After a month of daily 10-minute sessions, most players report near-perfect recall of the full list.

Here's a practical schedule:

• ▶Week 1: Learn A-words and E-words (26 words). Review daily.
• ▶Week 2: Add O-words and U-words (24 words). Review all learned words every other day.
• ▶Week 3: Add consonant-initial words (remaining ~77). Review full list twice this week.
• ▶Week 4: Review only the words you've missed. Play games and note any you forgot.

Method 5: Active Gameplay

The best reinforcement is actual use. When playing Scrabble (online or in person), actively look for two-letter word opportunities before considering longer words. This forces recall under time pressure — exactly the condition you need to perform in.

Try this exercise: play 5 games where you prioritise parallel plays using two-letter words over all other moves. Your scores might dip initially as you learn the patterns, but within a few games you'll start spotting opportunities you previously missed entirely.

Tracking Your Progress

Set a target: know all 127 within a month. Track which ones you miss repeatedly — these are your "sticky" words that need extra attention. Use our word finder to verify any word you're unsure about — type two letters and get instant confirmation with no signup required.

Most players find that after memorising the full list, their average game score increases by 30-50 points. That's the compound effect of seeing parallel plays, managing tiles better, and playing confidently without hesitation.
