Forms

proptereā (not comparable)[1] It is also written separately, propter eā.[2][3]

Etymology

It is from Latin propter (“because of”) + eā (“these things”), the ablative of is, like anteā and posteā.[2][3][1] De Vaan derives propter from prope (“near”), which he traces, after Dunkel, to Proto-Indo-European *própro (“ever further forward”).[4]

Earliest recorded meaning

Köbler dates it from Plautus,[5] who has quia mihi nātālis est diēs, proptereā tē vocārī ad cēnam volō, “because it is my birthday, I want you invited to dinner”.[6]

Semantic evolution

Proptereā means “for that reason, on that account, therefore”, usually joining cause and result.[2][6] It often looks forward to a clause: proptereā quod or quia, “because”, and proptereā ut, “with this in view, in order that” (Plautus, Terence, Cicero).[2] Lewis & Short give ideō, idcircō and inde as synonyms.[6]

Church Latin glosses it “therefore, for that cause”.[7]
