AT is a short function word rather than a productive prefix, so English has built very little on it. The 5 letter words starting with AT form the smallest field of any two letter opening, small enough that a player can learn the whole set.
O takes the third position in more than a third of them. Atoms, Atone, Atlas and Attic are the ones most players already know, though more than half the set repeats a letter, which makes a guess with five separate letters harder to find here than anywhere else.
There are 24 five letter words starting with AT. Atoms, Atone, Atlas, Attic and Atria are the strongest Wordle guesses, though only eleven of the 24 avoid a repeated letter. ATO holds the one real run, so test O in the third slot first.

5 Letter Words Starting With AT For Wordle
These eleven use five different letters, and they are the only AT words that do. 5 letter words starting with P answers a nearby question. Five letter words with T as the second letter leaves the first letter open.
| Atoms | Atone | Atmos |
| Atopy | Atomy | Atony |
| Atimy | Atocs | Atoke |
| Atoks | Atrip |
Atoll, Attar and Attic all repeat a letter, and so do half the rest. On a field this small that changes the odds rather than just the risk.
