This attribute is used to distinguish between common and proper nouns. MULTILEX encodes this information among the syntactic attributes of its lexical unit (LU). AlethDic splits the nouns into two different categories: `nom' and `nom propre' (this diverging treatment is signalled in the table with an asterisk). However, no transduction (see Monachini & Östling (1992b)) and convergence problems arise between these two approaches, since they are easily intertranslatable.
