← Word lists

Words starting with C, then M, then A, ending in S

462 words fit this spine. The 240 most recognizable are listed below, longest and commonest first. They start with C, end with S, and contain M then A in that order in between — not necessarily side by side.

Near misses
  • caballero doesn't fit: it starts with C but ends with O, not S.
  • cabinets doesn't fit: it has the right ends but no M in the middle.
  • calamitous doesn't fit: it has every letter of CMAS but they don't appear in order inside it.
