Why “foreshower” is a great word
FORESHOWER — [Noun] One who, or that which, predicts or indicates a future event. From the verb 'foreshow' (to predict or presage) + the agentive suffix '-er' (one who does an action). First attested in 1555. Unlike 'prophet' (which implies divine inspiration or authority) or 'omen' (which refers strictly to the portentous object or event itself), a foreshower is the general, secular agent of prediction. It is the ache in an old sailor's knee before the storm, the first goose veering south in a still-warm sky, and the quiet friend whose every casual warning later proves true—an unaccredited herald of the inevitable, bearing news no one has yet asked to hear.
