Etymology

From Proto-Italic *-ōs, from Proto-Indo-European *-ōs, for original *-oss, compound suffix from *(é)-os (athematic) (neuter s-stem) + *-s (masculine nominative).
The ō from the nominative case was made common to all cases originally with non-ablauting o (the three exceptions were arbor, mulier and Cerēs). Afterwards nom.sg. -ōr > -or, by Latin sound laws. Thus paradoxically, as in other r-stems (soror, -tor), in the resulting paradigm the one form with a short stem vowel is the only form whose stem was etymologically long.
