shunt

Imagine a train track with a switch - that is the basic idea behind "shunt." To shunt something is to move it away from its usual course and send it along a different path. This can be literal, like moving a train onto a side track, or figurative. In medicine, a doctor might shunt fluid away from an area where it is causing pressure. People can also shunt blame, problems, or tasks onto someone else, meaning they avoid dealing with them directly and pass them on. The word suggests deliberate redirection, sometimes for a practical reason and sometimes to avoid something unpleasant.

The word "shunt" originally comes from railway terminology - it describes the act of moving railroad cars from one track to another by using a switch. Think of a train being moved off the main line onto a side track for repairs or storage; that is being shunted.

However, "shunt" has expanded far beyond the tracks. In electrical engineering, a shunt is a device or path that lets current go around a particular part of a circuit, often to protect equipment or to help measure current. In medicine, a shunt is an implanted tube or a created passage that gives fluid, such as blood or cerebrospinal fluid, a new route so it can bypass a blockage. For example, a doctor might place a shunt to drain excess fluid from the brain to the abdominal cavity.

Figuratively, "shunt" means to avoid dealing with something directly by passing it to someone else or by pushing it into a less important place. "He tried to shunt the blame onto his colleague" means he tried to make his colleague responsible instead of taking ownership himself. It can also mean to brush something aside, as in "The committee shunted her concerns aside."

So, whether you are talking about trains, electricity, medicine, or responsibility, "shunt" usually implies deliberate redirection away from the normal path - sometimes helpful, sometimes evasive.
