One who bodes or foretells; someone who reads omens or predicts the future; an archaic term.
Derived from 'bode' with the agent suffix '-er' (one who does something), following Middle English patterns of creating occupational or descriptive nouns.
A 'boder' was basically an ancient fortune teller, but the word shows how every profession eventually gets a name in English—we do the same thing today with 'influencer' and 'content creator'!
