Word Origin & History

sterile
1426, "barren" (implied in sterility), from M.Fr. stérile "not producing fruit," from L. sterilis "barren, unproductive," from PIE *ster- "sterile, barren" originally "stiff, rigid" (cf. Gk. steresthai "be deprived of," steira "sterile," stereos "firm, solid, stiff, hard;" Skt. starih "a barren
cow;" O.C.S. sterica "a barren cow;" Goth. stairo "barren;" O.N. stirtla "a barren cow"). See torpor. Originally in Eng. with ref. to soil; of females, from 1535. The sense of "sterilized" is first recorded 1877. Sterilize "destroy the fertility of" is from 1695 (in ref. to soil); of living things from 1828. Meaning "render free of microorganisms" is from 1878. Sterilization is from 1874.
