Zusammenfassung: 
LEU/2 is a language processing computer system which is lexically creative and, therefore, able to form and to comprehend words which are not elements of the fixed inventory of the LEU/2 lexicon. The lexical creativity of the system, arises from two features radically different from each other and, consequently, complementary to each other. On the one hand, the system is lexically creative because LEU/2 is able to extend its lexicon by means of its knowledge of certain rules of word formation. In this respect the LEU/2 lexicology has an explanatory force, as this lexicology gives, at least on a highly abstract level of representation, an answer to the question how the lexical creativity of the native speaker/hearer is structured. On the other hand, the system is able to extend its lexicon incrementally, namely by means of an access to external lexica and an interactive use of the user input. These mechanisms optimize the lexical power of the system, but, trivially, they do not induce explanations of the lexical creativity of the native speaker/hearer. The LEU/2 lexicology is, therefore, the result of a mixed methodology, as this lexicology is partly explanatory and partly a non-explanatory procedure to optimize the lexical capacity of the system.
