vast 遼闊的

來(lái)自拉丁語(yǔ)vastus,荒廢的，空無(wú)的，引申詞義遼闊的，無(wú)垠的，詞源同vain,waste.

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.
