Origins

The suffix -arus is also found in the river Silarus. The base *tem- is said by Pokorny to be from Proto-Indo-European *teh₂- (“to flow, stream, melt”), but this is unlikely. It is possibly instead borrowed from Proto-Celtic *tamaros (“river, waters”, literally “dark”), from a zero-grade form similar to Proto-Indo-European *tm̥Hrós (“the dark river”), from *temH- (“dark”). Also compare the cognates listed at Thames.
