drive-in adj.

Old English drifan "to compel or urge to move, impel in some direction or manner; to hunt (deer), pursue; to rush against" (class I strong verb; past tense draf, past participle drifen), from Proto-Germanic *dreibanan (source also of Old Frisian driva"I lead, impel, drive (away)," Old Saxon driban, Dutch drijven, Old High German triban, German treiben, Old Norse drifa, Gothic dreiban "to drive"), perhaps from PIE root *dhreibh- "to drive, push," but it may be a Germanic isolated word.

Used in Old English of nails, ships, plows, vehicles, cattle; in Middle English of bargains. Meaning "compel or incite to action or condition of any kind" (drive mad) is by late 12c. Sense of "work with energy, labor actively" is c. 1200; that of "aim a blow" is by early 14c.. Transitive meaning "convey (someone) in a carriage," later an automobile, is from 1660s. The original sense of "pushing from behind" was altered in Modern English by application to automobiles. Related: Driving.

a Middle English merger of Old English in (prep.) "in, into, upon, on, at, among; about, during;" and Old English inne (adv.) "within, inside," from Proto-Germanic *in (source also of Old Frisian, Dutch, German, Gothic in, Old Norse i), from PIE root *en "in." The simpler form took on both senses in Middle English.

Sense distinction between in and on is from later Middle English, and nuances in use of in and at still distinguish British and American English (in school/at school). Sometimes in Middle English shortened to i.

The noun sense of "influence, access (to power or authorities)," as in have an in with, is first recorded 1929 in American English. to be in for it "certain to meet with something unpleasant" is from 1690s. To be in with "on friendly terms with" is from 1670s. Ins and outs "intricacies, complications of an action or course" is from 1660s. In-and-out (n.) "copulation" is attested from 1610s.
