Words related to pack
late 14c., nowghty, noughti "needy, having nothing," also "evil, immoral, corrupt, unclean," from nought, naught "evil, an evil act; nothingness; a trifle; insignificant person; the number zero" (from Old English nawiht "nothing;" see naught)) + -y (2).
Specific meaning "sexually promiscuous" is from 1869. The mitigated sense of "disobedient, bad in conduct or speech, improper, mischievous" (especially of the delinquencies of children) is attested from 1630s. Related: Naughtily; naughtiness. In 16c.-18c. a woman of bad character might be called a naughty pack (also sometimes used of men and later of children).
"an agreement between persons or parties," early 15c., from Old French pacte "agreement, treaty, compact" (14c.) and directly from Latin pactum "agreement, contract, covenant," noun use of neuter past participle of pacisci "to covenant, to agree, make a treaty," from PIE root *pag- "to fasten." Related: Paction "act of making a pact."
"bond money, security given to obtain the release of a prisoner," late 15c., a sense that apparently developed from that of "temporary release (of an arrested person) from jail" (into the custody of another, who gives security for future appearance at trial), which is recorded from early 15c. That seems to have evolved from the earlier meanings "captivity, custody" (late 14c.), "charge, guardianship" (early 14c.).
The word is from Old French baillier "to control, to guard, deliver" (12c.), from Latin baiulare "to bear a burden," from baiulus "porter, carrier, one who bears burdens (for pay)," which is of uncertain origin; perhaps a borrowing from Germanic and cognate with the root of English pack, or perhaps from Celtic. De Vaan writes that, in either case, "PIE origin seems unlikely."
To go to(or in) bail "be released on bail" is attested from mid-15c. In late 18c. criminal slang, to give leg bail meant "to run away."
mid-15c., paket, "a little package or parcel" (late 12c. as a surname), "in earliest use applied to a parcel of letters or dispatches, and esp. to the State parcel or 'mail' of dispatches to and from foreign countries" [OED], from Middle English pak "bundle" (see pack (n.)) + diminutive suffix -et; perhaps modeled on Anglo-French pacquet (Old French pacquet), which ultimately is a diminutive of Middle Dutch pak or some other continental Germanic word cognate with the English one. A packet boat (1640s) originally was one that carried mails from country to country or port to port, then generally a vessel starting at regular dates and appointed times. In data transmission, packet-switching is attested from 1971.
