inter- (English)
Where does "inter-" come from?
The English prefix 'inter-' traces its origins back to the Proto-Indo-European root '*h₁en-'[1]. Through the extended form '*h₁entér', meaning 'between', it developed into Proto-Italic '*ənter' and subsequently into the Latin preposition and prefix 'inter', signifying 'between' or 'amid'[1][3][4]. English eventually borrowed this form directly from Latin[1].
