7-letter words with C as the 1st letter and O as the 4th letter

Pin down the first and fourth slots, and the remaining five letters can still produce very different words. COLONEL, CHRONIC, COLORED, COCONUT, and CROOKED all fit. The list has 141 tournament-dictionary entries, but just 13 meet our common-word frequency cutoff, so many valid matches will be unfamiliar outside word games.

• Collins covers 139 matches; NWL2023 covers 115, and ENABLE covers 102. Dictionary totals overlap.

• An average tile score of 11.8 gives a baseline before board bonuses.

Which familiar words fit this letter pattern?

Try COLONEL, CHRONIC, COLORED, COLOURS, COCONUT, or CALORIE as recognizable examples. Their shared frame leaves the second, third, fifth, sixth, and seventh letters open, so the fixed O does not make the rest of the word predictable.

The last letter offers a useful clue: 51 candidates end in S. E appears at the end of 15, while D appears on 14. If your final tile is S, start with the largest group, then use revealed letters to narrow it.

How do these matches compare for word games?

COROZOS tops the listed Scrabble tile scores at 18 points. CAJOLED, CHROMYL, and CHOOKED each score 17, although those specialist words are less familiar than COLONEL or COCONUT. Premium squares and placement affect the final board result, so treat tile scores as a starting point, not the points you are guaranteed to earn.

Dictionary choice changes which candidates are playable: Collins has 139 matches, NWL2023 has 115, and ENABLE has 102. These are overlapping sets, not counts to add together. The limitation is practical: a valid match in one dictionary may fail in another, so check your game's word list before playing an obscure option.
