Analyse phraséologique du marqueur discursif ce m'est avis et de ses variantes dans un corpus d'ancien français.

The article shows that the construction ce m'est avis functions as a discourse marker in an original corpus of 13th French prose novels. We adopt a double approach, phraseological and stylistic, to study how this marker performs in discursive sequences representing oral speech (characters' dialogue or narrator's words). The comparison with the construction que P (il/ce) m'est avis que allows us to note their common origin and then their progressive specialization. Finally, an overview of the diachronic evolution of ce m'est avis shows its decline and its replacement by à / selon mon avis. [ABSTRACT FROM AUTHOR]
