Propositional attitude verbs express lexical evidentiality. This property may have nuances, which depend on whether these verbs, in their performative forms, are in parenthetical constructions, whether or not they omit the pronominal subject or if the pronominal subject is before the verb or postponed. Verbs with this meaning and their frequency of occurrence were described within the PRESEEA-Medellín corpus. Five verbs of propositional attitude were found: believe, think, imagine, assume and consider.
