Constructed action (CA) is a discourse strategy in sign languages in which signers use parts of their body to depicit actions, utterances, thoughts, feelings and/or attitudes of a referent. This strategy has been well researched among the sign languages. The aim of this research was to describe CA during narration in croatian sign language (HZJ) and to compare the obtained data with the data available from previous sign language research. Question was whether CA exists in HZJ, and, if it does, how and why do signers take on roles of the referents. For the purpose of this study, six recordings elicitated by two clips of an american cartoon 'The Simpsons' were analysed using ELAN software. Three participants took part in this study and each of them retold two different stories. Acquired data was then analysed using descriptive methods. Results show that signers do take on roles during storytelling in HZJ. In this reseach signers used CA to depicit actions, emotions, thoughts and utterances of the cartoon characters. In doing so, the three signers very often took on roles to show the happenings of the same scenes. For the display of CA signers used all of the recorded nonmanual markers: eyegaze, head, face, torso and arms. Non-manual marker that was used in all retellings by all participants was eyegaze, while the other non-manual markers appeared active in 87 to 97 percent of roles taken. Listed results match with the prior discoveries on CA in sign languages. The biggest similarities were noticed in the purpose of using CA and the manner in which the roles are taken on. This research contributes to the linguistic description of HZJ, confirms the complex linguistic structure of the language and, by raising new questions, encourages new research. New knowledge gained by this research can be applied in teaching HZJ as a second language. Furthermore, the new discoveries obtained by this research show the importance of using sign language in (re)habilitation and education of deaf people.
