trawl: [17] Trawl was probably borrowed from Middle Dutch traghelen ‘drag’. This was a derivative of traghel ‘net pulled along behind a boat for catching fish’, which in turn came from Latin trāgula, a possible relative of trahere ‘pull’ (source of English tractor, treat, etc). Trāgula probably also lies behind English trail [14]. => trail[trawl etymology, trawl origin, 英语词源]
