OLD POLISH LANGUAGE SPECIFICITY AND GRAMMATICAL ANNOTATION: ON THE NEED FOR NEW CATEGORY VALUES The paper is focused on the grammatical annotation of Old Polish texts. The authors discuss the necessity to use unusual grammatical category values: 0 and X. It occurs when any of the values is impossible to determine (e.g. due to damage to the manuscript or insufficient syntactic/semantic context) or a word takes no value in a given category (e.g. an unstated adjective). The article presents factors influencing the choice of 0 and X values. It shows those grammatical classes and categories in whose annotation the use of these values has been highly significant.
