A gag is something that stops someone from speaking or makes them unable to talk.
The word "gag" has a few different uses. When it's a noun, it can refer to a physical object like a stick or cloth used to block someone's mouth and prevent them from shouting out. Imagine being at a magic show and the magician uses a gag to make his assistant silent. On stage, the comedian might also use a prop that looks like a gag to add humor to their act.
However, when "gag" is a verb, it means to stop someone from speaking or expressing themselves freely. You might say you can't gag on something if it's disgusting and you don't want to look at it closely. In a more serious sense, people in power might use the term "gag order" for an official rule that stops others from talking about sensitive information.
A device to restrain speech, such as a rag in the mouth secured with tape or a rubber ball threaded onto a cord or strap.
To experience the vomiting reflex.
Example: He gagged when he saw the open wound.
