captivate

Learned borrowing from Late Latin captīvātus, the perfect passive participle of captīvō (“to capture”), from Latin captīvus (“captive, prisoner”) (ultimately from capiō (“to capture, seize”), from Proto-Indo-European *kap- (“to hold; to seize”)) + -ō (suffix forming first-conjugation verbs). Equivalent to captive + -ate (verb-forming suffix).
