History
Etymology
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”) + -īvus (suffix forming adjectives). Invāsus is the perfect passive participle of invādō (“to enter; to invade”), from in- (prefix meaning ‘in, inside’) + vādō (“to go; to rush; to walk”) (ultimately from Proto-Indo-European *weh2dh- (“to go, proceed; to pass, traverse”)). The noun is derived from the adjective.
