This article deals with a processing of pronouns in the Pralex lexical database. Pronouns can be homonymous with other word types, e.g. with nouns or adverbs. Grammatical data for polysemic pronouns are introduced at the level of a full entry or at the level of individual meanings. Within every lexical unit, the author records a pronoun type as well as its primary syntactic function. Sometimes, identification of a word type can be problematic, e.g. the pronouns který (who) and jaký (which), which are used to link a subordinate clause, but have no relative function at all. When defining an explanation of a meaning, we rely on Dictionary of the Standard Czech Language and Dictionary of Standard Czech for Schools and the General Public. An example part of entries is divided in the so-called modified and sentential records.
