英文词源
- vast
- vast: [16] Latin vastus originally meant ‘empty, unoccupied, deserted’. The sense ‘huge’, in which English borrowed it, is a secondary semantic development. Another metaphorical route took it to ‘ravaged, destroyed’, in which sense it lies behind English devastate and waste.
=> devastate, waste - vast (adj.)
- 1570s, "being of great extent or size," from Middle French vaste, from Latin vastus "immense, extensive, huge," also "desolate, unoccupied, empty." The two meanings probably originally attached to two separate words, one with a long -a- one with a short -a-, that merged in early Latin (see waste (v.)). Meaning "very great in quantity or number" is from 1630s; that of "very great in degree" is from 1670s. Very popular early 18c. as an intensifier. Related: Vastly; vastness; vasty.
