## AI Etymology
intromission comes from Latin intromissus, past participle of intromittere 'to send in, admit', from intro- 'inward' plus mittere 'to send'. Morphologically, the prefixed shape matters: the initial element belongs to the recorded formation and helps explain the modern form's surface analysis.
