flint (English)

Where does "flint" come from?

The word 'flint' traces back to the Proto-Indo-European root *(s)plind-, which means 'to split' or 'to cleave.' This root evolved through Proto-Germanic as *flintaz before passing into Old and Middle English, retaining a connection to the stone's physical property of fracturing easily. Today, the term reflects this ancient history by describing both the resilient stone itself and the physical act of splitting or sparking.
