Abstract: This paper deals with three of the four categories of phrasemes called by Agnès Tutin (in this journal issue) Phrases Préfabriquées des Interactions (PPI), such as on aura tout vu, ça va pas la tête. Having examined the challenges posed by the metalinguistic, reactive and situational PPI in terms of linguistic research, Denis Le Pesant presents his own online Dictionary of the PPI, together with some tools for the processing of large corpora.
