The term "stop cock" is commonly used to refer to a valve that regulates the flow of liquid or gas. The word "stop" is straightforward and pronounced /stɒp/, but the pronunciation of "cock" can be tricky. Despite its spelling, the word is pronounced /kɒk/ and not /kɔk/. This is because the "o" in "cock" is followed by a consonant sound, which means it is pronounced with a short vowel sound. So, when referring to a valve, it's important to use the correct pronunciation to avoid any confusion.
A stop cock is a mechanical valve or tap used to regulate or control the flow of a liquid or gas in a pipe or plumbing system. It is designed to stop, control, or redirect the flow of the substance passing through it by opening, closing, or partially obstructing the pathway.
Stop cocks are commonly found in plumbing systems, especially in households, commercial buildings, and industrial facilities. They play a crucial role in shutting off the water supply to specific areas or appliances, allowing for maintenance and repairs. They are typically operated by turning a handle or lever, which either opens or closes the valve mechanism, depending on the desired outcome.
This type of valve provides a convenient and efficient means of regulating and stopping the flow of fluids or gases within a system. Stop cocks are often used in situations where a quick and dependable shut-off is required, such as emergencies, repairs, or when isolating specific sections of piping.
The term "stop cock" is widely used in British English. In American English, a similar device is referred to as a "stop valve" or "shut-off valve." Regardless of the name used, the purpose of a stop cock remains the same: to control the flow of substances through a plumbing or piping network.
An instr. used to regulate the supply of water or gas flowing through pipes.

The term "stop cock" is derived from the Middle English word "cok" (cock or valve), which is ultimately derived from the Old English word "coc" and the Proto-Germanic word "kokaz". The addition of "stop" refers to the function of the valve, which is to stop or regulate the flow of a liquid or gas in a pipe or conduit.
