liquid是什么意思

英文词源

liquid

liquid: [14] Latin liquēre meant ‘be fluid’. From it was derived the adjective liquidus, which reached English via Old French (it was not used as a noun in the sense ‘liquid substance’ until the early 18th century). Also derived from liquēre was the noun liquor, which passed into Old French as licur or licour. English has borrowed this twice: first in the 13th century as licour, which was subsequently ‘re-latinized’ as liquor, and then in the 18th century in the form of its modern French descendant liqueur.

From the same ultimate source come liquefy [16], liquidate [16] (which goes back to a metaphorical sense of Latin liquēre, ‘be clear’ – thus ‘clear a debt’; the modern meaning ‘destroy’ was directly inspired by Russian likvidirovat’), and the final syllable of prolix[15].
=> liquor, prolix
