In theatre terminology, what are sides of the stage called?

The term that describes the sides of the stage is "wings." Wings refer to the areas located off to the left and right of the stage where actors and stage crew can wait and prepare to make their entrances or exits without being seen by the audience. This space is crucial for the smooth and professional operation of a theatrical performance, allowing for quick transitions and maintaining the illusion of the performance.

The other terms refer to different parts of the stage and its surroundings. Backstage is the area behind the stage where actors prepare and crew work. The orchestra generally refers to the area in front of the stage where the audience sits, and it can also refer to a group of musicians performing. The front of the stage is simply the area closest to the audience and does not encompass the side areas that are specifically referred to as wings.
