5-letter words with I as the 1st letter and O as the 4th letter

The pattern is I??O?, so the second, third, and final letters are open. Examples include IDIOT, INBOX, IDIOM, and IGLOO, but only two of the 14 matches count as common by our frequency measure. That makes this a narrow clue with a few familiar options and several less familiar ones.

5-letter words with I first and O fourth

• The fixed pattern is I??O?, with I in position one and O in position four.
• Fourteen tournament-dictionary matches fit; only two qualify as common by our frequency measure.
• T is the most frequent final letter: three words end in T; N and S each finish two.
• ENABLE accepts 10 matches; Collins and NWL2023 each accept 12.
• The average score is 7.8, and INBOX is the top scorer at 14 points.

Which I??O? Words can you try in Wordle?

Five matches appear in the Wordle answer list, while 13 are allowed guesses. Those counts describe different pools: an answer-list match is not the same thing as every permitted guess. The fixed pattern narrows both, but the answer count does not identify which example words belong to it.

Dictionary coverage varies too: ENABLE has 10 matches, while Collins and NWL2023 each have 12. Those totals overlap, so do not add them together as separate words. If a game rejects a candidate, check its own word list rather than assuming the I??O? pattern is wrong.

How do the scores compare?

INBOX scores 14 points, ahead of ICHOR at 10. IPPON, INDOW, and IMPOT each score 9; IDIOM, INFOS, and INCOG each score 8. The average is 7.8, making INBOX a clear scoring outlier among these examples.

For 5-letter words with I as the 1st letter and O as the 4th letter, raw tile values are only part of the play. INBOX is the top base scorer, but a premium square can change the result; consider where its high-value X lands before spending the word.

Keep the ending open while solving: T occurs three times, while N and S occur twice each. If those letters are ruled out, the remaining endings are singletons, including G, L, M, O, and R. That distribution makes the final tile a useful filter after you lock in I and O.
