7-letter words with C as the 2nd letter and O as the 4th letter

The fixed pattern is _C_O___: the second tile is C, and the fourth is O. ACCOUNT, SCHOLAR, and SCOOTER show how much the other five positions can vary. Collins contains all 67 matches, but only 9 fall in the common-word group, so expect specialist vocabulary alongside familiar entries.

7-letter words with C as the 2nd letter and O as the 4th letter

• Collins recognizes all 67 words; ENABLE includes 37, while NWL2023 includes 41.
• Only 9 are common by word-frequency ranking, including ACCOUNT and SCHOOLS.
• S leads as the first letter with 29 matches, ahead of A with 21 and E with 14.
• ECHOIZE tops the scoring list at 21 points; ACROBAT and ACRONYM are familiar alternatives.

Which starting letters appear most often?

S supplies 29 of the 67 openings, with A contributing 21 and E contributing 14; just 3 begin with O. When the first letter is unknown, test an S-starting candidate first, then check the A and E branches.

Recognizable options include SCHOOLS, SCHOLAR, and SCOOTER for S, plus ACCOUNT, ACROBAT, and ACRONYM for A. OCTOPUS is one of only 3 O-starting fits, while ECHOING represents E.

The ending pattern is lopsided too: 18 words finish in S, compared with 10 ending in D and 8 in E. Check a final S early if that slot is open. For comparison, the version with E in the second position has 349 matches, far more than this C pattern.

How should you use the fixed letters?

For a constrained rack or crossword, lock the known letters first, then compare candidates against the open slots. ACCOUNT repeats C, while SCHOOLS repeats O; those familiar spellings make the pattern easy to verify. Avoid rejecting a match just because its first or last letter is unexpected.

Scoring favors less ordinary entries: ECHOIZE scores 21, and ECTOZOA scores 18. Those are valid dictionary examples, not everyday choices, so check your game's word list before committing. Since only 9 entries are common, most of the remaining options are better treated as pattern matches than routine vocabulary.
