    <Paragraph position="0"> Several important issues have been discussed in this paper, regarding the structure and the function of the lexicon, as well as the role of morphology. We first pointed out the important role of morphology and showed that it cannot be dispensed with, even in processing systems with no particular psychological claim. Hence, an exhaustive list of all the orthographic forms of English words cannot stand for an adequate lexicon of English.</Paragraph>
    <Paragraph position="1"> Turning then to what appears to be the traditional conception of morphology in computational linguistics, we showed that a morpheme-based lexicon, along with a derivational morphological component faces a variety of serious problems, including its inability to distinguish actual words from potential words, its inability to express partial morphological or semantic relations, as well as its inherent inefficiency and often lack of reliability.</Paragraph>
    <Paragraph position="2"> The success of this traditional conception of the lexicon in computational linguistics must probably be attributed to its relative conciseness. However, alternative ways to evaluate the complexity of lexical entries, i.e.</Paragraph>
    <Paragraph position="3"> Jackendoff's independent information content, as well as the emergence of cheap and abundant memory have drastically modify this state of affair, and open new perspectives more in line with current research in theoretical linguistics.</Paragraph>
    <Paragraph position="4"> To the traditional view, we opposed a relational word-based lexicon, along the lines of Jackendoff's (1975) proposal, where morphology can be viewed, in part, as relations among lexical entries. Simple words, complex words, compounds, etc., are all listed in our lexicon. But lexical entries which belong to a same paradigm are related to the same lexeme. Rather than deriving or analyzing words each time they are used, morphological rules only serve when a new word occurs.</Paragraph>
