Watershed
noun /ˈwɔː.tə.ʃɛd/ — A pivotal moment dividing before and after; a ridge dividing water flows.
Definition
An event or period marking a decisive turning point — after which things are different in a fundamental way. In geography: the ridge of land separating waters that flow to different rivers or seas. Both senses carry the same idea: the point from which things flow in different directions.
Beyond the definition
A watershed is recognisable as such only in retrospect — you cross it and only later understand that you did. Before this. After this. The moment everything split.
Origin & history
English: 'water' + 'shed' (a divide, from Old English 'sceadan' — to separate). Originally geographical; the figurative use of watershed as a turning point developed in the 19th century.
