Etymology

Uncertain. Possibly from Vulgar Latin root *rhizomāre, from Ancient Greek ῥίζα ‎(rhíza, “root, base, foundation”) (compare Greek ρίζωμα ‎(rízōma, “rhizome”)), or alternatively, through metathesis, from a Vulgar Latin root *remediāre, from Latin remedium. Compare Aromanian aradzim, arãdzimari.
