6-letter words with C as the 1st letter and S as the 3rd letter

The C _ S _ _ _ shape sorts itself by vowel: CAS gives 28 matches, COS gives 30, CUS gives 17, CES gives 11 and CIS gives 5. Only CYSTIC and CYSTID break that pattern with a Y between the fixed letters. Twelve matches rank as common English, and the whole set averages 9.7 points, so familiarity rarely means value here.

How the C-S frame spreads across vowels

• Ninety-three six-letter words put C first and S third.
• COS covers 30 matches and CAS covers 28, leaving 35 for the rest.
• Every match keeps a vowel or a Y in the second slot.
• Twenty-seven end in S, 13 in D and 8 in R.
• CASQUE tops the score list at 17 points.

How many 6-letter words start with C and have S third?

The answer is 93. S is a quiet pick for the third slot, since C with R third reaches 202 matches and C with A third reaches 198, while L gives 95 and M gives 88.

The second letter does most of the sorting. CAS supplies 28 matches and COS supplies 30, so 58 of the 93 sit on those two pairs.

Endings run noun-and-verb, with 27 matches closing in S, 13 in D and 8 in R. CASTLE, CASINO, CUSTOM and COSMIC are the everyday faces of the group.

Where do the top scores sit in C-S words?

CASQUE leads on 17 points and is the only entry that leans on a Q. CASHEW, CUSHTY, CUSHAW, CASEFY and CASHAW all reach 14, and nothing else gets past 13.

The common words stay modest. All 12 score 12 points or less, from CASTLE and CASTOR on 8 to CASKET on 12, and CUSHTY is Collins-only.

That flatness is the honest limit of this frame: at an average of 9.7 points a word, it reads a puzzle well but rarely squeezes value out of a rack.
