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

The fixed O-I pair narrows six-letter play to 68 tournament-dictionary words, but only seven rank among common English terms. HEROIC, MEMOIR, and RECOIL are familiar anchors; other entries, such as DEVOIR and LIPOIC, are less everyday. Endings make this set lopsided: 30 finish with D, so checking the final square quickly trims your candidate list.

Which words fit the O-I pattern?

Familiar choices include HEROIC, MEMOIR, DEVOID, and RECOIL. Their different first letters show how much of the word remains open: the pattern fixes only positions four and five, leaving three letters before O and one after I.

The ending distribution is unusually concentrated. D closes 30 entries, while L and N each close 11; together, those three endings account for most of the set. Words such as ADJOIN and CUBOID illustrate the D group, while RECOIL ends in L.

Dictionary coverage differs: Collins includes 66 matches, NWL2023 includes 51, and ENABLE includes 48. The counts overlap, so they should not be added together. Many entries are uncommon, and acceptance depends on your game’s word list; check it before relying on a specialist term.
