This contribution aims to address the following question: "What types of linguistic units constitute a step in writing process?". The authors propose a pragmatics of the textualization process, emphasizing the significance of operations in constructing meaning during the production of text. Using the example of "enunciative irruptions", they explore the difference between edition (i.e. mental elaboration of the linguistic signs to be emitted) and emission units, revealing instances where verbal elements are born during emission. The study concludes with a phenomenology of textualization, interpreting these operations as meaningful behaviors that reflect the writer's process of discovery and self-construction. The authors argue for a closer examination of production writings, despite the lack of direct temporal data, as it aligns the analyst with the writer's use of this type of documents experience and emphasizes the importance of textualization operations over pauses in understanding the dynamics of written production.
