The Clue Wedding party?
The Answer INLAW
The answer "INLAW" fits the clue "Wedding party" because it refers to family members related by marriage. When two people get married, they each gain new relatives, such as in-laws. This term includes parents-in-law, siblings-in-law, and others who become part of the family through marriage. Thus, "INLAW" is a clever way to describe the extended family that comes together during a wedding.
