Etymologically, the entry records: PIE word *h₁én The adjective is derived from Middle English invasif (“of a weapon: offensive”), from Middle French invasif, Old French invasif (“invasive”) (modern French invasif), from Medieval Latin invāsīvus, from Latin invāsus (“entered; invaded”) + -ī… 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.
