Usage

What does prop mean? In theater and film, a prop is any item on the set of a production other than the costumes and scenery. It especially refers to an object handled or used by actors during their performance. This can be just about anything: a sword, a supercomputer, and a coffee mug are all examples of things that can be used as props in a production. Sometimes, these are real objects (like the coffee mug), but sometimes they are specially made for the production (like the supercomputer). The word can also be used more generally to refer to an item used in a similar way, such as during a presentation or photoshoot. Example: At my improv class, we have a box of items we can use as props during each scene. Unrelatedly, prop is also a common verb meaning to support something or hold it up, especially by using something else. This sense of the verb is most commonly used in the verb phrase prop up, as in One of the legs is broken so we had to prop up the table with the trash can. It can also be used figuratively, as in Holiday sales are the only thing propping up the company. Prop can also mean rest or lean something against something else that serves as a support, as in I don’t have a stand for my guitar so I just prop it against the wall. Something that serves as a support for something in this way can be called a prop, as in We’ll need to use a prop to keep it stable. Example: Prop the door open with a chair so we don’t get locked out.

Etymology

Origin of prop1

First recorded in 1400–50; late Middle English noun prop(p)e “support, support for a vine or plant”; cognate with Middle Dutch proppe “bottle stopper,” early Modern Dutch “support for vines”

Origin of prop3

Explanation

A prop is something you use as a support, like a broom that serves as a prop to hold a door open. A prop is also something that goes on stage, like a garbage can in a Beckett play. When you use a prop, you can say you prop something, or prop it up: "Here, prop your blanket fort up with this chair." This handy word also means "a moveable object used on the set of a movie or play." If you get a film job as a prop master, you'll be in charge of placing props in the correct spot before a scene is shot. This theatrical meaning is actually a shortened form of properties.
