## AI Etymology
Expiry comes from expire + -y, ultimately from Latin exspirare ('to breathe out, die'), from ex- ('out') + spirare ('to breathe'). Morphologically, the account is both compositional and suffixal: ex- and -y marks the visible structure by which the older base becomes the modern form. In present use, it is used as a noun meaning "the end of the period for which something is valid", so the historical material remains connected with the current sense rather than standing as bare ancestry. The wider English family includes related forms such as expire, expiration, and expiratory, showing how the same historical material continues to organize neighboring vocabulary. The named historical forms include Latin exspirare and Latin spirare, keeping the history tied to concrete forms rather than a loose resemblance. Its semantic neighborhood is marked by expiration, termination, end, and cessation on one side and contrasts such as commencement, beginning, and renewal on the other, locating the modern specialization without adding a new origin story.
