Genderlects is a little studied phenomenon, whereby the gender of the speaker and/or of the addressee is obligatorily indexed in utterances that do not necessarily refer to the speech act participants. Interestingly, Fleming (2012: 297) has considered genderlects to be mostly limited to the Americas. Dunn (2014) and Rose (2015) suggest that this phenomenon may be more common in South America, or more specifically in Amazonia, than in the rest of the Americas. The primary aim of our paper is to assess this areal distribution with a balanced sample. Preliminary results confirm the two hypotheses on the geographical distribution of the genderlects.
