Reir la risa de un niño, chorar lágrimas de crocodilo um revisitar dos objetos cognatos entre expressões lexicalizadas e construções com verbos leves

gnate objects (OC) (espirrar um espirro...) can be paraphrased by light verbs (dar um espirro). However, some paraphrases appear to be ungrammatical or generate several readings (brito & Choupina 2018; Gonçalves et al. 2010; Mirto 2007). Cognate objects are of various types (Choupina 2013a and b), with real cognates being more restrictive syntactically and semantically. There are more or less inflexible expressions that resemble structures with OC (reir la risa.., chorar lágrimas de crocodilo...) and that occur in certain languages, not being subject to the same morphosyntactic restrictions of good formation as the OC and distinguishing them for the conditions of use. It is the properties that OC, constructions with light verbs and lexicalized expressions share and those that individualize them that we will deal with in this article
