What does pinning mean?
Pinning is the act of securing something with a pin, as when a notice is attached to a board or a piece of cloth is fastened to a saddle. It also has several figurative uses. To “pin down” something is to identify or establish it precisely, while “pinning hopes on” someone or something means placing reliance on them, often with an implied risk that they may not succeed. “Pinning” can also describe holding someone or something firmly in place. In informal British and American English, the word has a euphemistic sexual sense. The word illustrates how a simple physical action can develop specialized meanings: physically fixing an object becomes figurative fixation, precision, or dependence. It is useful in writing because phrases such as “pinning down the evidence” communicate both firmness and accuracy more vividly than abstract alternatives.

Where does pinning come from?
Pinning is formed from pin by adding the present-participle and gerund ending -ing. The base word pin comes from Old English pinn and originally referred to a pointed fastener or pin. English later extended the word from literal fastening to broader senses of securing, restricting, or holding firmly, which developed into the modern figurative meanings.
