Aroid

A plant of the arum family (Araceae), which includes common houseplants like philodendrons and peace lilies.

From 'arum' (the type plant, from Greek 'aron') plus the suffix '-oid' (meaning 'resembling'). The suffix '-oid' comes from Greek 'eidos' meaning 'form' or 'shape,' creating a name for the whole family of arum-like plants.
