-xë

oneself, myself, themselves

- ("ks") reflextive pronominal ending, presumably meaning *"oneself, myself, themselves" etc.; plural -xer, dual -xet (VT49:48). Presumably it can be used in constructions like *i nér tirnexë *"the man watched himself" (tirnesexë "he watched himself"), plural i neri tirnexer "the men watched themselves" (tirneltexer "they watched themselves"), dual e.g. i ontaru tirnexet "the parents watched themselves" (tirnettexet** "they [dual] watched themselves").
