sterile (English)

Where does "sterile" come from?

The English adjective 'sterile' traces its lineage back to the Latin term 'sterilis', which carried the sense of 'barren' or 'futile'[1]. This Latin form itself is derived from the Proto-Indo-European root '*ster-'[2]. The word entered English by way of the Middle French 'stérile'[1]. While the ultimate origin of the root remains a subject of linguistic investigation, it is often associated with the Ancient Greek 'στεῖρα'[3].

Open questions

• The Proto-Indo-European root is suggested to relate to either the sense of being stiff and unmoving or to a less supported sense of robbing. [3]
