From*(é)-os-s from*(é)-os(neuters-stem) +*-s(non-neuter nominative), with simplification of the geminate consonant /s/ and compensatory lengthening. Compare*-yōs.
The use of*-ōs as a derivational suffix to form nouns is supported by very limited evidence in Proto-Indo-European or any descendants other than Latin (where-or, -ōris became a somewhat common means of deriving masculine abstract nouns from the stems of verbs or occasionally adjectives) and descendants of Latin.
