Definition & Meaning of "put a sock in it"in English

What is the origin of the idiom "put a sock in it" and when to use it?

"Put a sock in it" is an English idiom that appeared in the early 20th century, likely originating from the practice of literally putting a sock in a gramophone or other horn to muffle the sound. The phrase came to be used figuratively to tell someone to stop making noise or talking, especially if they are being loud, irritating, or annoying. It is common in informal speech, British and American English, and humorous writing. The expression is mildly brusque but not strongly offensive, context-dependent, and often conveys irritation or playful scolding rather than serious hostility.
