AbstractThis article discusses the issue of improving the definition of legal terms in the existing Uzbek dictionary. Recommendations are given to improve the interpretation using examples. The norm of the dictionary is that it recommends the norms of spelling, pronunciation, word formation and its use in literary language. But it is not an easy task to notice the norm, to distinguish the normative cases. In particular, in the example of terms related to the field of law, which is the object of our research, we can say that the right mentioned in this explanatory dictionary. In the absence of signs indicating the legality of the lexical unit, which is the key word, or in the absence of these special signs, some cases related to the presence of words or phrases related to jurisprudence in the commentary were identified. But the terms 3types of criminal, given in the same line, are also given without the same lexical pomet as the same units (criminal and criminal). The logical conclusion is that these should also be considered legal terms, but in legal terminology these units do not occur. Thus, the presence of words and phrases in the dictionary, indicating the relevance of the field, which does not exclude the need to use a special sign as a unit.
