Konstrukcja objaśniająca rozumiej w staropolskich tekstach z kodeksu Wawrzyńca z Łaska

The aim of the article is to show functional divergence of the explaining structure: rozumiej (‘understand’) in the Old Polish apocryphal works from the code of Wawrzyniec from Łask: History of the Three Kings and The Gospel of Nicodemus. This structure was used to introduce new contents to a sentence (explaining a pronoun or a noun/verb). There were two main functions of this structure in analysed texts: organisation of the text, and a didactic role. The analysis leads to some conclusions about possible origins of these elements (it seems that they did not come from glosses or from the last copyist), and shows the need for further research of metatexts in Old Polish literature.
