   Note that, as Australian pronunciation merges the /ɒ/ and /əʊ/ phonemes before /l/ (they both become [oʊl]), this word is very commonly spelt "mole" in Australia, probably by contamination with the word mole, referring to sneaky people. Indeed, the Australian Oxford dictionary does not list the Australian meaning of the term under the headword "moll", but only under "mole", although it does recognise that "mole" in this sense is "probably" a mere "variant of ''moll''".
