"until," Old English til (Northumbrian), from Old Norse til "to, until," from Proto-Germanic *tilan (cf. Danish til, Old Frisian til "to, till," Gothic tils "convenient," German Ziel "limit, end, goal"). A common preposition in Scandinavian, probably originally the accusative case of a noun now lost except for Icelandic tili "scope," the noun used to express aim, direction, purpose (e.g. aldrtili "death," literally "end of life"). Also cf. German Ziel "end, limit, point aimed at, goal," and compare till (v.).
"cultivate (land)" (early 13c.), "plow" (late 14c.), from Old English tilian "tend, work at, get by labor," originally "strive after," related to till "fixed point, goal," and til "good, suitable," from Proto-Germanic *tilojanan (cf. Old Frisian tilia "to get, cultivate," Old Saxon tilian "to obtain," Middle Dutch, Dutch telen "to breed, raise, cultivate, cause," Old High German zilon "to strive," German zielen "to aim, strive"), from source of till (prep.). Related: Tilled; tilling.
"cashbox," mid-15c., from Anglo-French tylle "compartment," Old French tille "compartment, shelter on a ship," probably from Old Norse þilja "plank, floorboard," from Proto-Germanic *theljon. The other theory is that the word is from Middle English tillen "to draw," from Old English -tyllan (see toll (v.)), with a sense evolution as in drawer (see draw).
