Pronunciation

• (US) audio

Etymology

From New Latin trāiectōria f (“trajectory”) (used by Newton), the feminine of trāiectōrius (“of or pertaining to throwing across”), from Latin trāiectus (“thrown over or across”), past participle of trāiciō, from trans- (“across, beyond”) (see trans-) + iaciō (“to throw”) (from Proto-Indo-European *(H)yeh₁- (“to throw, impel”)). Middle French and Middle English had trajectorie (“end of a funnel”), from Latin trāiectōrium.

Meanings

1. The path an object takes as it moves.
   • The USA were dominant but, to England’s immense credit, they repeatedly rallied, refusing to fold. Indeed they could conceivably have gone in level at the interval had Naeher not made an acrobatic, stretching, fingertip save to divert Walsh’s 25-yard thunderbolt as it whizzed unerringly on its apparently inexorable trajectory towards the top corner. 2019 July 2, Louise Taylor, The Guardian:
2. The path of a body as it travels through space.
3. (qualifier:cybernetics) The ordered set of intermediate states assumed by a dynamical system as a result of time evolution.
4. (figuratively) A course of development, such as that of a war or career.
   • It is likely that the long evolutionary trajectory of Mycoplasma went from a reductive autotroph to oxidative heterotroph to a cell-wall–defective degenerate parasite. This evolutionary trajectory assumes the simplicity to complexity route of biogenesis, a point of view that is not universally accepted. 2013 March 14, Harold J. Morowitz, “The Smallest Cell”, in American Scientist, volume 101, number 2, archived from the original on 04 Jan 2017, page 83:
