Etymology
It is inherited from Proto-Italic *nosteros (“our”), formed from nōs with the contrastive suffix ⟨*-tero-⟩.[2][1][3] De Vaan tentatively reconstructs a PIE possessive *n̥s-tero-.[2]
Compare Ancient Greek ἡμέτερος (hēméteros, “our”), formed with the same suffix, and Old Irish ar n- (“our”).[3][2]
Earliest recorded meaning
It is found from Livius Andronicus on.[2][4]
Semantic evolution
Besides “our, ours”, noster is often used for “my” in formal or modest style.[3] Slaves use it of their own household (senex noster “our old master”), it marks affection with the name of a friend (Varrō noster “our dear Varro”), and it means “of our side, of our army”.[3]
The genitive plural nostrum is used by Plautus, and the noun nostrās “native, of our country” is derived from it.[3][2]
