SUMMARY
<b>Implications for Lexicography of the Classification of Plants and Animals in Folk Taxonomy</b> In this essay the scientific taxonomic system is contrasted with the folk taxonomic system through the use of relational semantic models: the basis for the former is chiefly meronymy, while that for the latter is mainly modification. Corresponding to these systems two kinds of dictionaries can be distinguished: the encyclopedic dictionary and the standard dictionary which are based on extensional and stereotypical concepts respectively. In a scientifically based culture the scientific taxonomical concepts influence the folk taxonomical concepts of plants and animals. This fact should be taken into account in definitions in a comprehensive explanatory dictionary which is based on prototypical concepts and takes a position between the encyclopedic dictionary and the standard dictionary.
