- rut: The rut of deer  and the rut of a wheel  are not related. The latter in fact is historically the same word as route. Both go back ultimately to Vulgar Latin *rupta, which was a noun use of the past participle of Latin rumpere ‘break’ (source also of English rout and rupture). The etymological notion underlying it is therefore of a path that has been ‘broken’ by constant use, a ‘beaten track’.
It passed into Old French as rute or rote, and it was this that gave English rut, which originally denoted the ‘track’ made by a wheel. The later French form route is the source of English route . Routine  comes from a French derivative of route. Rut ‘oestrus’ comes via Old French rut from Latin rugītus, a derivative of rugīre ‘roar’.
