Definition of the word put through

The origin of the phrase "put through" can be traced back to the mid-19th century, when it was first used in the context of telegraph communication. At the time, telegraph operators would use a key to send messages by transmitting electrical pulses along a wire. If a message was to be sent to someone who was not directly connected to the telegraph line, the operator would "put it through" to them by relaying it to another operator at an intermediate station, who would then forward it to its intended destination. This practice became known as "line repeating" or "line transfer," and eventually gave rise to the more general idiom "put through," which refers to any action taken to facilitate the transmission or delivery of something. In modern telecommunications, "put through" is still used to describe the process of forwarding a call or message to another party, typically with the assistance of an operator or automated system.
