Where it comes from
From mould (“loose friable soil; rotting earth regarded as the substance of the human body”) + -er (suffix forming frequentative verbs), probably influenced by mould (“furry growth of fungi”). Mould is derived from Middle English mold, molde (“loose friable soil, dirt, earth; earth as the substance out of which God made man, and to which the human body decays into after death”), from Old English molde (“earth, soil”), from Proto-Germanic *muldō (“dirt, soil; furry growth of fungi, mould”), from Proto-Indo-European *melh₂- (“to crush, grind”).
