The first guess is not about guessing the word — it is about buying information. Here is how to spend it well.
The mistake most players make with Wordle is treating the opening guess as a free attempt at the answer. It is not — it is an information purchase, and you should buy the most information you can.
That means optimising for letter coverage and position coverage, not for how plausible the word is.
Cover the common vowels first
Almost every English five-letter word contains at least one of A, E, I, O, U, and most contain two. Getting vowel information on guess one constrains the space more than any consonant choice.
Aim for an opening that contains at least two distinct vowels from the frequent set.
Spend consonants on the frequent letters
R, S, T, L, N and C account for a very large share of five-letter words. An opening built from three of these plus two vowels eliminates more candidates than any clever-sounding alternative.
Avoid repeating letters in your opener. A doubled letter buys half the information of two distinct letters in the same slot.
Use guess two to test positions, not new letters
Once you know which letters are present, the highest-value move is to place them in new positions. That converts yellow tiles into greens and narrows the list quickly.
Only introduce new letters on guess two if guess one came back almost entirely grey.
FAQ
Is there a single best opening word?
Several openings are within noise of each other. Pick one with two common vowels and three frequent consonants, learn it well, and stop worrying about the last fraction of a percent.
