7-letter words with I as the 2nd letter and O as the 6th letter

Keep the pattern _i___o_ in view: the second tile is I, the sixth is O, and the other five positions remain open. Familiar fits include MILLION, MISSION, BILLION, and FICTION, but only 10 of the 141 matches count among common English words. The rest range from ordinary vocabulary to specialist entries, so dictionary coverage matters when you play.

The pattern at a glance

• Exactly 141 words meet both fixed-letter positions.
• Only 10 matches fall within the common-word group.
• M begins 18 matches, the most of any first letter; D begins 13.
• N closes 33 words, compared with 26 ending in S.
• Collins lists 138 matches, versus 108 in NWL2023 and 99 in ENABLE.

Which familiar words fit this pattern?

Familiar examples make the pattern easier to scan. MILLION, MISSION, and BILLION share the ending -ION, while KINGDOM ends in M and FICTION ends in N. The pattern is not simply a suffix filter: O must sit in the sixth slot, so a word with O elsewhere does not qualify.

Look at the final letter when narrowing candidates: N closes 33 matches and S closes 26; T, R, and W close 12, 11, and 11. A first-letter clue is less concentrated: M leads with 18, but D, L, B, F, P, and V each begin at least 10 matches.

BILLION and MILLION also show how repeated Ls can fill the middle slots without shifting either fixed clue. VISITOR and SILICON offer different letter shapes, while all four examples preserve I in position two and O in position six.

7-letter words with I as the 2nd letter and O as the 6th letter

7-letter words with I as the 2nd letter and O as the 6th letter are a mixed bag for board play. KICKBOX scores 26, KILLJOY scores 21, and FIREBOX scores 19 before premium-square bonuses; the average score is 11.9. A high raw score is striking, but it does not make an unfamiliar word acceptable in every game.

The common-word count is small beside Collins' 138 matches: treat this as a constrained pattern, not a promise that every answer will feel familiar. Check your game's word list once, since Collins, NWL2023, and ENABLE accept different numbers of matches.
