Origin and history of trajectory

trajectory(n.)

in physics, "path described by a body moving under the influence of given forces," 1690s, from Modern Latin trajectorium, from trajectorius "of or pertaining to the act of throwing across," from Latin traiectus "thrown over or across," past participle of traicere "throw across, shoot across," from Latin trans "across, beyond" (see trans-) + icere, combining form of iacere "to throw" (from PIE root *ye- "to throw, impel").

Figurative or transferred use by 1838. Old French and Middle English medical writing had trajectorie as "end of a funnel," used to fumigate the ear, from Latin traiectorium. A verb traject was used in various senses of "pass or carry across, transmit," mostly in 17c.

also from 1690s

trans-

word-forming element meaning "across, beyond, through, on the other side of; go beyond," from Latin trans (prep.) "across, over, beyond," perhaps originally present participle of a verb *trare-, meaning "to cross," from PIE *tra-, variant of root *tere- (2) "cross over, pass through, overcome" [Watkins].

Besides its use in numerous English words taken from Latin words with this prefix, it is used to some extent as an English formative .... It is commonly used in its literal sense, but also as implying complete change, as in transfigure, transform, etc. [Century Dictionary]

In chemical use indicating "a compound in which two characteristic groups are situated on opposite sides of an axis of a molecule" [Flood].

Many trans- words in Middle English via Old French arrived originally as tres-, due to sound changes in French, but most English spellings were restored later; trespass and trestle being exceptions.
