How does this pattern compare with other O endings?

The O-fourth, S-fifth pattern has 199 words, compared with 114 that end in N and 63 that end in R. With O fixed in slot four, S leaves more candidates than either of those endings.

The fourth letter also changes the size of the search: 719 five-letter words have E in the fourth spot and S last. For the O-and-S pattern, A and M tie at 17 first-letter matches apiece, followed by D at 15 and T at 14. Check crossing letters early; the shared OS ending alone does little to narrow the opening three slots.

Only 11 entries are common in everyday English. CHAOS, KUDOS, TACOS, and ZEROS span different first letters and vowel patterns, making them easier to recognize than many entries in the group.

Which words score well, and what about Wordle?

MYXOS scores 17 in Scrabble, while BOZOS and MOZOS each score 16. ZEROS and EXPOS reach 14 points. The top scores lean on less familiar words, so check your game’s dictionary before relying on an unusual play; game dictionaries differ.

Wordle offers a much smaller answer set: only 2 of these words are answers, although 194 are allowed guesses. That makes the pattern better for testing a known ending than for picking an opening guess. If O and S are already confirmed, use the other revealed letters to choose among candidates rather than assuming every accepted guess can be an answer.

For 5-letter words with O 4th and S 5th, familiar options like CHAOS and TACOS are easier to spot, but they do not cover every possible first letter. Use the crossings to rule words out, and treat the score leaders as game-specific choices rather than everyday vocabulary.
