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”).

moulder²

  • /ˈməʊldə/ UK
  • /ˈmoʊldəɹ/ US

Rhymes with -əʊldə(ɹ)

Where it comes from

Partly from the following:

* From Middle English molder, moldere (“maker of bread, baker”), from molden (“to knead or shape (bread); to make bread, bake; to mix (something) by kneading; to shape, mould; to pulverize (?)”) + -er (suffix forming agent nouns, especially names of people engaged in professions or trades). Molden is derived from mold, molde (“model or pattern according to which a thing is made, mould”) + -en (suffix forming the infinitives of verbs); and mold, molde are borrowed from Old French molde, a variant of modle, molle (modern French moule), from Latin modulus (“small interval or measure; etc.”), diminutive of modus (“measure; manner, method”), ultimately from Proto-Indo-European *med- (“to measure”).

* From mould (“to shape in or on a mould; to form into a particular shape”, verb) + -er (suffix forming agent nouns).
