Good luck, good fortune, or a fortunate happening; an archaic term combining 'good' with 'hap' (luck or chance).
Compound of Middle English 'good' and 'hap' (from Old Norse 'happ' meaning luck or fortune), used in Early Modern English to wish someone favorable chance or occurrence.
Medieval people used 'hap' for luck the way we use 'vibes' today—'goodhap' was wishing someone good vibes, and it shows how the concept of luck was deeply baked into how people talked about fortune in medieval times.
