7-letter words with I as the 1st letter and O as the 6th letter

The pattern I _ _ _ _ O _ leaves a short, unusual set: all 13 matches appear in Collins, while seven are listed in both ENABLE and NWL2023. None ranks among the 25,000 most common English words, so familiar-looking entries such as INCISOR sit beside obscure game words. Use the fixed letters to narrow a rack, then check the word list used by your game.

At a glance: the I–O pattern

• 13 tournament-dictionary words start with I and place O in the sixth position.
• IMBIZOS leads the Scrabble scores at 20 points before board bonuses.
• INCISOR scores 9 points, while INKBLOT and INKSPOT each score 13.
• Four matches end in R; three end in S, and none is common by frequency.

Which I–O words score the most?

IMBIZOS is the standout scorer at 20 points, with the uncommon Z and B doing much of the work. ICHABOD and INKWOOD each score 15, while INKBLOT, INKSPOT, and IMBOSOM each reach 13.

For a more familiar play, INCISOR scores 9 and INDIGOS also scores 9. The average score is 11.8, but that figure hides the gap between these everyday-looking options and the high-value, less familiar IMBIZOS.

7-letter words with I as the 1st letter and O as the 6th letter

The full set is ICHABOD, INCISOR, INKBLOT, IGNITOR, INDIGOS, INKSPOT, ISOTRON, IGNAROS, IMBIZOS, IMBOSOM, IMPEDOR, INKWOOD, and ISOCHOR. Ten have dictionary definitions, but the pattern has no common entries, so expect several unfamiliar plays.

The sixth-letter O is a particularly restrictive clue: the I-first pattern with E there has 189 matches, compared with just 13 here. Check your game's dictionary before committing to a rare entry; Collins includes all 13, while ENABLE and NWL2023 include seven apiece.
