Ce que la linguistique de corpus peut nous dire sur les locutions en langue française écrite. Le cas de la locution adverbiale "à première vue"

This study aims to illustrate the results of an analysis conducted on a French corpus, focusing on the adverbial phrase à première vue. From a methodological point of view, our study is based on the corpus linguistics approach, drawing inspiration, in particular, from the model of extended units of meaning (Sinclair 1991), based on four semantic phenomena, namely collocation, colligation, semantic preference and semantic prosody. To achieve this, we will analyze a third-generation monolingual French corpus, identifying units in which the adverbial phrase serves as the lexical core. This study aims to demonstrate that phrases are part of an extended phraseology, where the identified units serve as a principle of text organization.
