From Proto-Italic *-ezi, from Proto-Indo-European *-esi, locative case of action noun. Similar to Ancient Greek -ειν (-ein).
From Proto-West Germanic *-ārī, from Proto-Germanic *-ārijaz.
Uncertain ultimate origin, usually held to be from Latin -ārius. Gąsiorowski instead suggests that *-ārijaz is a native formation; he derives it from earlier *-azrijaz, which he etymologises as a zero-grade form of *-sōr suffixed with *-ih₂, creating a suffix *-sr-ih₂ for forming feminine agent nouns, which were then masculinised by attaching *-ós. He also suggests a relation to Proto-West Germanic *-astrijā.
Cognate with Old Frisian -ere, Old Saxon -āri, Old High German -āri.
