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

This fixed pattern gives you a compact set: every entry begins with C and ends with O. Only 5 of the 27 words rank among the top 25,000 English words by frequency, so familiar picks such as casino and crypto stand out from less common options. The score leaders are less obvious than the everyday examples.

The C…O pattern at a glance

• Twenty-seven six-letter words satisfy the C-to-O frame in at least one tournament dictionary.
• Collins includes all 27; NWL2023 includes 21, and ENABLE includes 16.
• Five matches are among the top 25,000 English words by frequency.
• Casino, crypto, cardio, and calico are recognizable examples.
• Chocko and corozo lead the listed Scrabble scores at 17 points each.

Which C…O words score highest?

Chocko and corozo tie for the top score, with 17 points apiece before any board bonuses. Chocho follows at 16; cuckoo scores 14. Among the more recognizable picks, crypto scores 13, the same as cheapo, concho, chromo, and camsho.

A strong tile score does not make a word a safe play in every game. The three dictionaries split the set differently: Collins covers all 27, NWL2023 21, and ENABLE 16. Confirm the word list your game uses before playing an unfamiliar entry.

What does this pattern leave out?

The final O is unusually restrictive for six-letter words beginning with C: the C…S pattern has 561 matches, far more than these 27. If the last letter is uncertain, compare the C…O results with the lists ending in S or E before ruling out a candidate.

The 7-letter version of this same C-first, O-sixth pattern has 116 matches, so adding a letter opens up many more options. For the exact six-letter query, remember that only five matches are common by frequency; casino and cardio are easier to recognize than chocko or corozo.
