The fixed CO opening produces 463 six-letter matches, but the entries range from familiar words such as COMMON and COUNTY to less everyday plays. Only 69 meet our common-word cutoff. For a quick scan, check the final letter: S is the leading ending by a wide margin, while the highest tile score belongs to a much rarer-looking option.

At a glance: six-letter CO words

  • 463 six-letter entries fit the CO opening across tournament dictionaries.
  • 69 are common words, including COURSE, COMING, COMMON, COUNTY, and COUPLE.
  • Final S leads with 129 matches; E follows at 60, then R at 52.
  • COZZES tops the scoring list at 26 points, ahead of COCCYX at 22.

How does CO compare with other six-letter openings?

The CO pattern has 463 matches, compared with 285 for BO and 270 for PO at the same length. That makes C-O a notably productive opening among these neighboring patterns, while the two fixed letters still narrow a clue sharply.

The ending distribution offers another quick filter. S appears 129 times, more than twice as often as E at 60; R comes next at 52. If your puzzle shows a final S, try familiar candidates such as COLORS, COURTS, COPIES, or COUNTS before testing less common forms.

6-letter words with C as the 1st letter and O as the 2nd letter

COZZES scores 26 points, making it the top scorer in this group. COC CYX is listed at 22, while COWPOX, COZILY, CORYZA, and COZEYS each reach 20. These contrast with everyday choices like COFFEE and COUPLE: the familiar word is often easier to spot, but it is not necessarily the scoring leader.

Dictionary coverage differs: Collins includes 454 matches, NWL2023 has 360, and ENABLE has 335. The full 463-count combines tournament-listed entries, so a word accepted in one game may not transfer to another. Check your game's word list before relying on an unfamiliar scorer such as COZZES.
