They’ve missed at least one prominent example, namely the South American language Karajá [0]. Ribeiro’s grammar spends a whole chapter talking about the difference between female and male speech, which include: • Men can drop k, often causing vowel fusion and modification • Men drop d/n in the two words dõ ‘a’ and adõ ‘something’ • Various irregular vocabulary differences For instance, female dɪkarə̃ kadɪɗakakre corresponds to male dɪarə̃ adɪɗakakre ‘I will take it off’.
