6-letter words with I as the 1st letter and O as the 4th letter

The fixed letters leave four unknown slots between and after the pattern’s I and O. With only 47 matches, this is a narrow search rather than a broad six-letter browse. The recognizable set includes INCOME and INFORM, but several valid entries are much less familiar, so check the game’s dictionary when a candidate looks unusual.

The 47-match pattern, led by INCOME

• Forty-seven words fit the exact six-letter pattern: I _ _ O _ _.
• INCOME, IGNORE, INFORM, and IMPORT are among the listed examples.
• Eight matches rank among the top 25,000 English words by word frequency.
• Final S is most common, appearing on 14 words; E comes next with 10.
• Collins includes 47 matches, compared with 36 in NWL2023 and 35 in ENABLE.

6-letter words with I as the 1st letter and O as the 4th letter

INCOME, IGNORE, INFORM, IMPORT, INDOOR, IMPOSE, and INVOKE are among the clearest everyday-looking candidates. Each follows the same fixed pattern, but the remaining letters give you a useful spread of endings, from the E in INVOKE to the R in INDOOR.

The top examples also show why a pattern match is not the same as a familiar word. INDOLE, INMOST, and INTOED fit the slots too, although they are less likely to come to mind quickly. Only eight of the 47 matches fall within the top 25,000 English words by frequency.

How do dictionary versions and scores compare?

Collins has all 47 matches, while NWL2023 has 36 and ENABLE has 35. Those differences matter in word games: a candidate accepted in one list may not be accepted in another. The 47-word total counts entries found in at least one of these tournament dictionaries, not every possible word-like spelling.

IMBODY and IMBOSK tie for the highest score at 14 points. INVOKE and INWORK follow at 13, while IDIOCY, IGNOMY, INWOVE, and INLOCK score 12. The top-scoring pair is far less familiar than INCOME, so use score as a clue only when the word itself fits your game’s rules.

Among neighboring patterns, 176 six-letter words start with S and place O fourth, versus 47 starting with I. For this narrower I pattern, 14 words end in S; that ending is the strongest single choice when you know the final letter.
