English 'wedding' derives from Old English 'weddian' (to pledge) and 'wedd' (a pledge), from Proto-Germanic *wadją and PIE *wadh- meaning 'to pledge or give as security' — revealing that the word is fundamentally about contract and legal covenant, naming the marriage ceremony after the binding pledge made at its centre.
A marriage ceremony, together with any accompanying festivities; the event at which two people are married.
From Old English 'weddian' meaning 'to pledge, to covenant, to give a pledge,' from 'wedd' meaning 'a pledge, a surety.' The root is Proto-Germanic *wadją meaning 'a pledge,' from PIE *wadh- meaning 'to pledge, to redeem a pledge.' The word is fundamentally about contract and surety, not ceremony: a 'wedding' was originally the pledging of a guarantee, and the marriage ceremony was the event at which that pledge was formally made
