词源
late Middle English (originally Scots)： probably from Old English thyddan 'to thrust， push'; related to thoden 'violent wind'. The noun is recorded first denoting a sudden blast or gust of wind， later the sound of a thunderclap， whence a dull， heavy sound. The verb dates from the early 16th cent.
