6-letter words with C as the 5th letter and S as the 6th letter

The frame is _ _ _ C S, so the closing pair is always CS. LYRICS, TOPICS, ETHICS, and COMICS are the words players meet most, and 41 of the 68 end in the full -ICS. Eleven count as common, and ZEBECS at 19 leads the scores.

The _ _ _ C S frame

• 68 tournament words fit the frame _ _ _ C S.
• 41 of them end in -ICS, the group's defining feature.
• Only 12 words start with C, the largest opening group.
• Eleven words count as common.
• ZEBECS leads at 19 on its Z; XEBECS reaches 17.

The -ICS cluster at the heart of the set

The -ICS ending gives this group its character. LYRICS, TOPICS, ETHICS, COMICS, BASICS, and OPTICS are all familiar, and RELICS, ANTICS, MEDICS, and MIMICS fill out the run.

Most of those are plural nouns built from an -ic adjective, which is why the set feels like a shelf of school subjects and hobbies. CODECS sits just outside the pattern, closing on -ECS rather than -ICS. That shared shape means a solver who spots the tail often has the hardest part solved.

Scores and the spread of openings

ZEBECS tops the group at 19 and XEBECS reaches 17, both riding a Z or an X. TOXICS scores 15 and HAVOCS 14, while CIVICS, CYNICS, and MAFICS settle on 13. The X in TOXICS and the V in HAVOCS do the heavy lifting for those two.

The opening letters stay spread out: C takes 12, T nine, and M eight. A single first-letter clue never narrows the group by much, so the -ICS tail does most of the sorting work.
