Rarely, it is convenient to recognize a minus morpheme, which consists of the dropping of any phoneme occupying a particular position, e.g. the dropping of the last consonant, which constitutes a morpheme meaning ‘masculine’ in Bloomfield’s analysis of French adjectives. Morphemes involving replacement of one phoneme by another may then be considered as consisting of the dropping of one phoneme and the adding of the other (i.e. as combinations of the first two types). Thus 'men' contains two morphemes: 'man'; and – /æ/ + /e/, which means ‘plural’.
