The paper examines the perfect construction in the Patzún variety of Kaqchikel (Mayan; ergative) that has so far received no formal analysis. I propose that perfect in Kaqchikel is periphrastic: it should be analyzed as non-verbal predication with a result nominal used as the predicate and can be literally translated as 'x is [y's product/result of V-ing]'. The suffix -on is thus not a verbal inflection but a derivational morpheme, a result nominalizer. Analyzing perfect forms as nominal allows us to expand the discussion of be-perfect in the world's languages, which so far has mostly been informed by data from Indo-European languages of Europe.
