It is inherited from Proto-Italic *n̥ter (“between”), inherited from Proto-Indo-European *h₁entér (“between”), an adverb of place derived from *h₁en (“in”) (see in).[2][1][3] The related adjective in ⟨*-tero-⟩ survives in intrā, intrō and interior, and the superlative intimus is inherited too.[2]
Cognate with Oscan anter (“between”) and Umbrian anter-, Old Irish eter (“between”), Sanskrit अन्तर् (antár, “between, within”) and Albanian ndër (“between, among”).[2][3][1]
Earliest recorded meaning
It is found from Livius Andronicus on.[2][4]
Semantic evolution
Inter means “between, among, amid”, of place and of a group (inter paucōs “as few others”), with verbs of dividing “among”, and of time “during, in the course of”.[3][5] With sē it expresses a mutual relation, “with one another”.[5] As an adverb it is rare and poetic, “in between”.[5]
Niermeyer records the medieval sense “including, in all”.[6] As the prefix inter- it adds the senses of the preposition.[3]
