Word Origin for boot
footwear, early 14c., from Old French bote "boot" (12c.), with corresponding words in Provençal and Spanish, of unknown origin, perhaps from a Germanic source. Originally for riding boots only. An old Dorsetshire word for "half-boots" was skilty-boots [Halliwell, Wright].
"profit, use," Old English bot "help, relief, advantage; atonement," literally "a making better," from Proto-Germanic *boto (see better (adj.)). Cf. German Buße "penance, atonement," Gothic botha "advantage." Now mostly in phrase to boot (Old English to bote).
"start up a computer," 1975, from bootstrap (v.), a 1958 derived verb from bootstrap (n.) in the computer sense.
"to kick," 1877, American English, from boot (n.1). Generalized sense of "eject, kick out" is from 1880. Related: Booted; booting.
