In an article entitled "La nouvelle lexicographie", Bernard Quemada suggests that a phase of "pre-dictionary writing" precede the phase of dictionary-entry writing. At the Université de Sherbrooke, we have set up such a pre-dictionary description project. The BANQUE DE DONNÉES TEXTUELLES DE SHERBROOKE contains more than five million words and is composed of a variety of oral, literary, and non-literary texts. In order to describe the lexical units contained in this data bank, we have developed a pre-dictionary data sheet for frequently occurring nouns. I propose to describe our pre-dictionary work and to illustrate it by means of three frequently occurring terms in our bank that are characteristic of certain Quebec texts: francophone, anglophone, and allophone.
