Wedding and marriage are related concepts, but they refer to different aspects of a committed relationship.
A wedding is a ceremonial event that marks the beginning of a marriage. It is a public celebration where two individuals, often accompanied by their families and friends, exchange vows and promises to each other. The wedding typically includes rituals, traditions, and festivities that vary across cultures and religions.

On the other hand, marriage is the legal and social union of two people, recognizing their commitment to each other and establishing certain rights and responsibilities. It is a long-term commitment that goes beyond the wedding day and involves building a life together, sharing responsibilities, and supporting each other through thick and thin.

An example to illustrate the difference between the two is as follows:
Sarah and John decided to get married. They planned a beautiful wedding ceremony with all their loved ones present. During the wedding, they exchanged heartfelt vows and rings, symbolizing their commitment to each other. The celebration was joyous, and they felt surrounded by love and support. After the wedding, Sarah and John officially became married partners. They moved in together, shared their finances, and started planning for their future as a married couple. The day-to-day life as a married couple involved facing challenges, making compromises, and cherishing precious moments together. The wedding was a significant event that marked the beginning of their marriage journey, but the real essence of their relationship lied in the lifelong commitment they made to each other.

In summary, a wedding is the celebratory event that marks the start of a marriage, while marriage is the lifelong commitment and union between two individuals. The wedding is a momentous occasion that brings family and friends together to witness and celebrate the union, but the true substance of a relationship lies in the shared journey of a married life.
