Origins

Uncertain. Latin vowel reduction probably caused any short vowel in a word-internal open syllable to evolve regularly to -e- before -r- (compare -fer from Proto-Italic *-foros, socerī from Proto-Italic *swekurī), which suggests that this suffix had a comparatively recent analogical origin. (An alternative opinion holds that -u- was regularly retained before -r-, but Parker 1986 argues that examples like augurium can be explained by analogy, e.g. to the nominative augur.) *Possibly from Proto-Indo-European *-tew- (as in the supine) + *-rós. Possibly compare -tūrus and/or -tūra. According to De Melo 2007, Risch 1954 postulates the construction goes back to an unattested *saturiō (“to be full”) from satur, used as the basis for an analogical ēsuriō, originally with the sense "to be hungry" but then evolving to "to want to eat". *Possibly from -tor- (the original oblique stem of the agent suffix -tor, from Proto-Italic *-tōr) + -iō, from Proto-Indo-European *-yéti (denominative suffix).
