Engagement can mean:
- A promise made by two people to marry, before becoming husband and wife at their marriage.
- Having a job to perform work, or possibly music or other entertainment. (This is sometimes called a "gig".)
- To take part or be busy in something.
An engagement is an agreement or promise to marry, and also refers to the time between proposal and marriage. During this time, a couple is said to be affianced, engaged to be married, or simply engaged. An engagement can be seen by witnesses to confirm their marriage
A work engagement is being hired to perform a job, usually a brief or single-event one, such as a party or public event. A performance engagement or "gig" usually means a single-event entertainment job, such as musician, clown, dancer or other performance. (A "running engagement" is a steady job of this kind.)
