Etymology

expire = ex<out> + spire<breathe>

  • ex: Latin prefix meaning "out" or "away."
  • spire: Derived from Latin spirare ("to breathe"), retained in English as a root related to breath or life.

Etymology Origin:
The word expire originated from Latin exspirare ("to breathe out"), combining ex- (out) and spirare (to breathe). It initially referred to the literal act of exhaling or emitting breath. Over time, it metaphorically extended to mean "the end of life" (breathing one's last) and later generalized to "the end of validity" (e.g., contracts, licenses). This progression reflects the symbolic link between breath and vitality in ancient thought.
