7-letter words with I as the 3rd letter and O as the 6th letter

The fixed pattern is _ _ I _ _ O _, so the third letter is I and the sixth is O. Only 7 of the 75 matches are common by frequency, but several are familiar: opinion, edition, rainbow, and tuition. The rest range from everyday forms to less familiar game entries, making the ending and dictionary split worth checking before you play.

The pattern at a glance

• There are 75 seven-letter matches with I third and O sixth.
• Collins includes 73 matches; NWL2023 includes 58, while ENABLE includes 49.
• Opinion, edition, and rainbow are recognizable examples among the 7 common entries.
• The most frequent final letters are N with 22 words and S with 19.

Which endings and scores stand out?

N and S dominate the final position: 22 words end in N and 19 end in S. That makes endings a strong way to narrow a rack or crossword clue once the middle letters are fixed. Other notable endings include R, with 8 matches, and T and W, with 4 each.

For Scrabble, thiazol, chikhor, and quillow each score 19 points before board bonuses. Mailbox and chiffon score 18, while chinook, aliquot, and whitlow each reach 16. These high scorers are less familiar than opinion or edition, so don’t assume a high-value pattern word will be accepted in every game.

How to use 7-letter words with I third and O sixth

• Write the slots as _ _ I _ _ O _ before testing your other letters; a misplaced O rules out every match.
• Try familiar candidates such as opinion, edition, tuition, or rainbow before searching obscure entries.
• If your game uses NWL2023, its 58 matches are fewer than Collins’ 73; check your game’s word list.
• Seventeen of the 75 matches are absent from NWL2023, so a word accepted in Collins may fail in a North American game.
• Openers spread widely: S begins 10 words, A begins 9, and C and T begin 8 each, so no single first letter settles the search.
