sterile (English)

Where does "sterile" come from?

The word 'sterile' traces its roots back to a Proto-Indo-European term related to being stiff or lacking, eventually evolving into the Latin 'sterilis,' meaning barren or futile. It passed through Middle French before entering English, shifting from its original focus on biological infertility to include broader meanings like germ-free, unproductive, or even restricted security zones.
