The pattern is _ _ S _ _ C: S is locked into the third slot, and every match closes with C. The set spans 16 tournament-dictionary words, but just four meet our common-word frequency threshold. Familiar candidates include COSMIC, MOSAIC, RUSTIC, and MYSTIC, though the frequency count does not identify which four qualify.

The pattern at a glance

  • Sixteen six-letter entries match the fixed pattern _ _ S _ _ C.
  • Every match ends in C; no other final letter appears in the set.
  • Collins lists all 16, while ENABLE and NWL2023 each list 13.
  • Four entries fall within our common-word frequency threshold.
  • MYSTIC and CYSTIC lead the scoring list at 13 points apiece.

Which 6-letter words have S third and C last?

COSMIC, MYSTIC, MOSAIC, RUSTIC, and CYSTIC are clear starting points; each places S third and C sixth. Other matches include MASTIC, FISTIC, BUSTIC, and NOSTOC, so the middle letters—not the ending—do most of the work in distinguishing candidates.

First-letter counts are uneven: C begins four matches, while F and M begin three each. N starts two; B, G, L, and R start one apiece. If you know the first tile, that split narrows the search quickly, especially when it is C, F, or M.

For a solving grid, write the fixed S and final C first, then test familiar middle-letter patterns. COSMIC and MYSTIC give recognizable options, while less familiar entries such as FUSTOC and CASEIC are worth checking only after the common-looking candidates fail.

How do scores and dictionary counts compare?

At face value, MYSTIC and CYSTIC score 13 points each; COSMIC scores 12. The set averages 10.3 points, so the top two offer the strongest letter-value totals before premium squares change the result.

Dictionary coverage changes the usable pool: Collins accepts 16 matches, compared with 13 in both ENABLE and NWL2023. Three Collins entries are absent from each of those smaller sets. For 6-letter words with S as the 3rd letter and C as the 6th letter, check your game's word list before relying on a less familiar candidate.

Are all 16 words accepted in ENABLE and NWL2023?
