A wedding is a celebration or ceremony of marriage. Besides being a formal way to mark the union of two people, weddings can be a lot of fun too.
The earliest meaning of wedding was simply "the state of being married," but by the early 1400s it meant the ceremony or rite at the very beginning of a marriage. A wedding can be a simple civil ceremony at City Hall or an elaborate event that takes place over several days and involves religious rituals, food and drink, and hundreds of guests. As an adjective, wedding describes anything related to the ceremony, like wedding cakes and wedding dresses.
