drain是什么意思_drain怎么读_中英文释义(含例句用法)

drain: drain: [OE] The underlying meaning of drain seems to be ‘making dry’. It comes ultimately from *draug-, the same prehistoric Germanic base as produced English drought and dry, and in Old English it meant ‘strain through a cloth or similar porous medium’. There then follows a curious gap in the history of the word: there is no written record of its use between about 1000 AD and the end of the 14th century, and when it reemerged it began to give the first evidence of its main modern meaning ‘draw off a liquid’.
=> drought, dry
