What's the difference between expiration and extinction?

Expiration


Definition:

  • (n.) The act of expiring
  • (n.) The act or process of breathing out, or forcing air from the lungs through the nose or mouth; as, respiration consists of inspiration and expiration; -- opposed to inspiration.
  • (n.) Emission of volatile matter; exhalation.
  • (n.) The last emission of breath; death.
  • (n.) A coming to a close; cessation; extinction; termination; end.
  • (n.) That which is expired; matter breathed forth; that which is produced by breathing out, as a sound.

Extinction


Definition:

  • (n.) The act of extinguishing or making extinct; a putting an end to; the act of putting out or destroying light, fire, life, activity, influence, etc.

Example Sentences:
