apprenticeship (n.)

"one bound by legal agreement to an employer to learn a craft or trade," c. 1300, from Old French aprentiz "someone learning" (13c., Modern French apprenti, taking the older form as a plural), also as an adjective, "unskilled, inexperienced," from aprendre "to learn; to teach" (Modern French apprendre), contracted from Latin apprehendere "take hold of, grasp" mentally or physically, in Medieval Latin "to learn" (see apprehend). The shortened form prentice, prentis long was more usual in English.

word-forming element meaning "quality, condition; act, power, skill; office, position; relation between," Middle English -schipe, from Old English -sciepe, Anglian -scip "state, condition of being," from Proto-Germanic *-skepi- (cognates: Old Norse -skapr, Danish -skab, Old Frisian -skip, Dutch -schap, German -schaft), from *skap- "to create, ordain, appoint," from PIE root *(s)kep-, forming words meaning "to cut, scrape, hack" (see shape (v.)). It often forms abstracts to go with corresponding concretes (friend/friendship, etc.).

word-forming element meaning "state or condition of being," from Old English -had "condition, quality, position" (as in cildhad "childhood," preosthad "priesthood," werhad "manhood"), cognate with German -heit/-keit, Dutch -heid, Old Frisian and Old Saxon -hed, all from Proto-Germanic *haidus "manner, quality," literally "bright appearance," from PIE (s)kai- (1) "bright, shining" (Cognates: Sanskrit ketu "brightness, appearance"). Originally a free-standing word (see hade); in Modern English it survives only in this suffix.
