Etymology
Following Forssman, de Vaan explains it from a verb *propriāre (“to make one's own”), built on inherited from Proto-Italic *prijo- (“own, dear”), inherited from Proto-Indo-European *priH-o- (“own, dear”), with the prefix prō-.[2][3] The OLD and Lewis & Short call it of doubtful origin.[4][5]
Cognate with Sanskrit प्रिय (priyá, “dear, own”), Welsh rhydd (“free”) and Gothic 𐍆𐍂𐌴𐌹𐍃 (freis, “free”).[2]
Earliest recorded meaning
It is found from Plautus onwards.[2] A Plautine character asks why what he wants cannot be his own for good.[4]
Semantic evolution
It meant one's own for good, belonging to oneself, and in the neuter one's own property.[4] It meant one's own alone, personal and private, as in Sallust's virtue as the one thing proper to mortals, and peculiar to someone.[4][5]
It also meant suitable, special to one case, belonging to a person's task, and of words, specific, as names which refer to particular things in Varro.[4] In medieval Latin homo proprius was a serf or a dependant, and proprio iure meant in full ownership.[6] English proper came from it through Old French around 1300.[7]
