Etymologically, the entry records: 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-) + iac… Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is trajectory, spelled T-R-A-J-E-C-T-O-R-Y, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
