• In this paper, I address verbal predicates of change in Southern Aymara, an understudied Andean language. I concentrate on verbs that are derived with the suffix -cha. This suffix derives degree achievements and creation predicates. I propose that they should be analyzed uniformly as degree achievements. The main empirical point of this paper is that there are two degree morphemes that combine with verbs with -cha, namely, a covert positive morpheme v.POS and an overt suffix -su. The latter is a degree morpheme that restricts the standard of comparison to lexical or contextual maximal degrees. I propose an analysis in terms of Maximize Presupposition: v.POS and -su constitute lexical alternatives where the latter is preferred over the former when maximal values are reached. v.POS is thus felicitous when no maximum is reached. The discussion bears on how telicity is achieved cross-linguistically when degree achievements are considered, thus enriching our typologies on the topic.
