wedding: [OE] A wedding is etymologically a ceremony at which people ‘promise’ to marry each other. The word’s source, the verb wed [OE], goes back to prehistoric Germanic *wathjōjan (source also of German wetten ‘wager’). This in turn was derived from the noun *wathjam ‘pledge’, which also produced English engage, wage, and wager. => engage, wage, wager[wedding etymology, wedding origin, 英语词源]
