英文词源

trend

trend: [OE] The etymological notion underlying trend is of ‘circularity’ or ‘roundness’. It comes from a prehistoric Germanic base *trend-, *trund-, which also produced Dutch trent ‘circumference’, Swedish trind ‘round’, and English trundle [16], and it was originally used in the sense ‘revolve, roll’. This gradually evolved via ‘turn’ to, in the 16th century, ‘turn in a particular direction, take a particular course’. The first record of the derivative trendy dates from 1962.
