membrum (Latin)

Where does "membrum" come from?

The Latin noun 'membrum' traces its origins to the Proto-Italic '*memzrom'[1]. This form developed from the Proto-Indo-European root '*mḗms' or '*mēms-rom', which carried the original meaning of 'flesh'[1]. This Proto-Indo-European foundation itself is thought to derive from an earlier root '*mems-'[2].
