Somewhat disputed. Probably from the root of *rūgō + -men, attested in ērūgō, rūctō (“I belch”) and rugiō (“I roar, rumble, bray”), from Proto-Indo-European *h₁rewg-, *h₁rewǵ- (“to belch”).[1] Cognate with Ancient Greek ἐρεύγομαι (ereúgomai, “I spew out, discharge, belch, bellow”), Old Armenian ործամ (orcam, “I vomit, am nauseated”), Proto-Germanic *reukaną (“to smoke, emit vapor”) (modern English reek).
Alternatively from Proto-Indo-European *sréwmn̥, from the root *srew- (“to flow”). (Can this(+) etymology be sourced?) See also Rōma and flūmen, which are sometimes hypothesized as from the same source.
A third possibility is a relationship with Etruscan (rum, “teat”). If not coincidental, it may be equally likely that the Etruscan word was borrowed from Latin.
