Liquidate is a learned borrowing from Late Latin liquidātus, the perfect passive participle of liquidō (“to turn into a liquid, melt; to make clear”), from Classical Latin liquidus (“fluid, liquid; clear, transparent”) + -ō (suffix forming regular first-conjugation verbs). * Alternatively, a borrowing from Middle French liquidation, from liquider (“to liquidate”) + -ation (suffix forming nouns denoting an action or process). Liquider is probably a borrowing from Italian liquidare, itself also from the aforementioned Late Latin liquidō by borrowing.
