In many Indo-European languages, proximity is a relevant feature of pronominal systems (e.g., Macedonian proximal vs. distal determiners, cf. English this vs. that). In several indigeneous languages of North America, proximity is represented by verbal agreement (then also known as obviation, e.g., Blackfoot third [proximal] and "fourth" [distal 3rd] person). As defined here, proximity is considered a morphosyntactic feature, because it applies to morphosyntactic *markers* of proximity. (Chiarcos)
