Talk:turning point

What kind of turning?
Our def suggests that this is a point when a directional turn occurs, i.e. a reversal or deviation. But Chambers 1908's def is "the point on which a question turns, and which decides the case: a grave and critical period", i.e. a sense of turn more akin to. This would be good to clarify in the etymology or elsewhere. Equinox ◑ 03:11, 22 December 2018 (UTC)
