mid-15c., from Middle English pak "bundle" (see pack (n.)) + diminutive suffix -et; perhaps modeled on Anglo-French pacquet (Middle French pacquet), which ultimately is a diminutive of Middle Dutch pak. A packet boat (1640s) originally was one that carried mails. Packet-switching attested from 1971.
