7-letter words with I as the 3rd letter and O as the 5th letter

The pattern is _ _ I _ O _ _: the fixed vowels leave the first, second, fourth, sixth, and last positions open. Fourteen matches rank among common English words, so familiar choices such as EPISODE and UNIFORM sit beside less routine entries like RHIZOME and CHINOOK. The full set draws on three tournament dictionaries, and acceptance can differ between them.

7-letter words with I as the 3rd letter and O as the 5th letter

• 146 matches fit the pattern in at least one tournament dictionary.
• 14 are common by frequency; EPISODE, UNIFORM, and TRILOGY are familiar examples.
• 63 end in S, the largest final-letter group by a wide margin.
• 21 begin with T, ahead of S at 20 and E at 15.
• Quixote scores highest at 23 points; the average score is 11.6.

Which endings narrow the pattern fastest?

The final letter gives you a strong first filter: 63 matches end in S, while 32 end in E. Those are the two largest ending groups, but an S ending does not guarantee a plural; EPISODE and UNIFORM show how varied the set is.

Starting letters are less concentrated. T leads with 21, followed by S at 20, E at 15, and C at 14. If a crossing letter fixes the first tile, check T and S first rather than working alphabetically.

Only 14 of the 146 matches are common by frequency. That makes familiar examples a small slice of the pattern; expect less routine vocabulary once your crossing letters rule out EPISODE, UNIFORM, or TRILOGY.

How should you judge scores and game fit?

Quixote leads the score ranking at 23 points, followed by PHIZOGS at 22 and RHIZOME and RHIZOMA at 21 each. The high scorers are not all familiar words: the unusual letters in Quixote and PHIZOGS boost their totals, while RHIZOME offers a recognizable alternative.

For 7-letter words with I as the 3rd letter and O as the 5th letter, treat the full set as a cross-dictionary pool, not a guarantee for every game. Matches come from ENABLE, Collins, and NWL2023, so a word accepted in one list may not appear in another. Check your game's lexicon before playing an unfamiliar entry.
