space (English)

Where does "space" come from?

The English noun 'space' descends from Middle English 'space'[1], which was influenced by Anglo-Norman 'space' and Old French 'espace'[1][3]. These forms ultimately trace back to the Latin noun 'spatium'[1][3]. Latin 'spatium' is connected to the Proto-Indo-European root '*(s)peh₂-', meaning 'to stretch, to pull'[1][2], reflecting the fundamental notion of an extended physical or temporal expanse.
