Origin and history of Jacob

masc. proper name, attested by 1218, probably via Anglo-French Jake, Jaikes, from Old French Jacques (which was a diminutive of Latin Jacobus; see Jacob), but in English the name always has been regarded as a familiar form of John, and some have argued that it is a native formation. In Middle English spelled Jakke, Jacke, etc., and pronounced as two syllables ("Jackie").

In England, Jack became a generic name applied familiarly or contemptuously to anybody (especially a young man of the lower classes) from late 14c. Later used especially of sailors (1650s; Jack-tar is from 1781); Jack-ashore (adj.) "drinking and in high spirits, recklessly spending" (1875) also is an image from sailors (1840 as a book title). In U.S., as a generic name addressed to an unknown stranger, attested from 1889. Every man Jack "everyone" is from 1812. Also see jack (n.).

Used in male personifications from 15c.; first record of jack-of-all-trades "person handy at any kind of work or business" is from 1610s (Tom of all trades is by 1630s); Jack Frost is from 1826; Jack-nasty "a sneak or sloven" is from 1833 (Jack-nasty-face, a sea-term for a common sailor, is from 1788). Jack Sprat for a small, light man is from 1560s (his opposite was Jack Weight). Jack-pudding "comical clown, buffoon" is from 1630s, translating Italian Zan Salcizza, a comical character in theater and literature (see zany). Jack-Spaniard is from 1703 as a Spaniard, 1833 as "a hornet" in the West Indies.

Other personifications listed in Farmer & Henley include jack-snip "a botching tailor," Jack-in-office "overbearing petty official" (1680s), Jack-on-both-sides "a neutral," Jack-out-of-doors "a vagrant" (1630s), jack-sauce "impudent fellow" (1590s). A supple-jack was a type of strong, pliant cane (1748) and a child's toy, among other things.

The U.S. plant jack-in-the-pulpit (Indian turnip) is attested by 1833. Jack the Ripper was active in London 1888; the name comes from the "Dear Boss" letter alleged to have been written by him. The Scottish form is Jock (compare jockey (n.)). Alliterative coupling of Jack and Jill is from 15c. (Iakke and Gylle, Ienken and Iulyan). Jack Ketch for "hangman, executioner" (1670s) is said to be from the name of a public executioner in the time of James II (compare derrick); it also was used as a verb meaning "to hang."

masc. proper name, New Testament name of two of Christ's disciples, late 12c. Middle English vernacular form of Late Latin Jacomus (source of Old French James, Spanish Jaime, Italian Giacomo), altered from Latin Jacobus (see Jacob).

The Welsh form was Iago, the Cornish Jago. James the Greater (July 25) was son of Zebedee and brother of St. John; James the Less (May 1) is obscure and scarcely mentioned in Scripture; he is said to have been called that for being shorter or younger than the other. Fictional British spy James Bond dates from 1953, created by British author Ian Fleming (1908-1964), who plausibly is said to have taken the name from that of U.S. ornithologist James Bond (1900-1989), an expert on Caribbean birds.
