En este trabajo se estudia la relación entre la morfología y la lexicografía mediante el análisis de seis verbos prefijados con re-. Se comparan sus definiciones en tres diccionarios y se proponen nuevas definiciones siguiendo el modelo de entrada lexicográfica del Diccionario de Aprendizaje de Español como Lengua Extranjera.

Dictionaries are an essential tool in the process of learning a foreign language and they /nmust meet the needs of its users. However, it happens too often that they do not include /nactualized and current information. The aim of this paper is to observe the relation /nbetween morphology and lexicography by analyzing a group of verbs prefixed by re- /nand its subsequent application to the Spanish learner‟s dictionary DAELE (Diccionario /nde Aprendizaje de Español como Lengua Extranjera). Four procedures are followed to /nachieve it: the summary of the syntactic, morphologic, and semantic information of re- /nprefix that appears in Spanish grammars; the analysis by different corpora of six verbs, /nchosen from the index of entries of this dictionary; the comparison of the existing /ndefinitions in three monolingual Spanish dictionaries and the proposal of a /nlexicographical entry for each analyzed verb. Using corpora enables the observation of /nthe gaps between existing definitions in the dictionaries and the real and current use of /nthe verb. Re- prefix has multiple meanings and affects the lexical base in a lot of /ndifferent ways; however, these nuances are not always showed on dictionaries‟ /ndefinitions.
