Words starting with T, then N, then I, ending in S

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

Near misses
  • tabby doesn't fit: it starts with T but ends with Y, not S.
  • tablecloths doesn't fit: it has the right ends but no N in the middle.
  • tardiness doesn't fit: it has every letter of TNIS but they don't appear in order inside it.
