Etymologically, the entry records: From French altruisme, which was coined in 1830 by Auguste Comte from autrui (“of or to others”) + -isme, from Old French, from Latin alteri, dative of alter (“other”) (whence also English alter). Apparently inspired by the French Latin legal phrase l'autru… 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 altruism, spelled A-L-T-R-U-I-S-M, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
