PIE word *h₁epi From Latin obtrūsus + English -ive (suffix meaning ‘of the nature of’, forming adjectives). Obtrūsus is the perfect passive participle of obtrūdō, a variant of obstrūdō (“to push, shove, or thrust against or into”), from ob- (prefix meaning ‘against; towards’) + trūdō (“to push, shove, or thrust”) (ultimately from Proto-Indo-European *trewd- (“to push; to thrust”)).
