How to use this word list

Tips for word games

Use constraints in order

Lock in greens first, then yellow positions, then rule out grays. Re-filter mentally against this list as you learn more letters.

Balance vowels and consonants

Early guesses often mix common vowels with high-frequency consonants (like R, S, T, L, N) to maximize information per turn.

Watch for doubles

Some answers repeat a letter. If you are stuck, browse the “double letters” pattern or try pairs from your confirmed letters.

FAQ

How many words match “Containing I and O” in your list?

We count 98 words on this page. Examples on this page include ABOIL, ALOIN, AMIDO, AMINO, ANION, AUDIO, and others. Always confirm against your game’s in-app dictionary; publishers can change valid word lists.

When should I use vowel-combination filters?

After you know two or more vowels must appear, intersection filters like “contains A and E” help avoid guesses that waste slots on letters you already confirmed elsewhere.

What if this page shows very few words?

Tight patterns (for example, all five vowels in one word) are rare in English. If the count is low, that is expected — switch to a broader pattern or letter-position filters.
