Etymology of ‘trend’
Etymology is the study of the origin of words and how their meanings evolved.
The Online Etymology Dictionary says the verb ‘trend‘ emerged in the English language in the 1590s. At the time, it meant “to run or bend in a certain direction (of costs, rivers, etc.).”
It came from the Middle English word ‘Trenden,’ which meant “to revolve, turn, roll about.” ‘Trenden’ came from the Old English word ‘Trendan,’ which meant “roll, revolve, turn around.”
The Old English word came from the Middle Low German ‘Trint‘ and Middle Low German word ‘Trent,’ which meant “boundary, ring.” Connections outside Germanic are uncertain.
The noun appeared in 1777 and meant “the way something bends.” It was not until the 1950s that the word also meant “a prevailing new tendency in popular fashion or culture.”
