The article presents syntactic and semantic characteristics of the verb faire (to make, to do, to manufacture, to act) in contemporary standard French, as well as colloquial language. For example: J’ai fait un livre: “I’ve made” a book, that is: I’ve published a book. Psychomechanics (psychosystematics) of Gustave Guillame’s language exhibits the so called ideogenesis (“the birth of ideas”, which leads to morphogenesis, “the birth of linguistics forms and meanings”) of the verb faire. Gérard Moignet (see the list of references, 1981) and other Guillame scholars claim that ideogenesis can be analysed into four continuous linguistic expressions (the complete ideogenesis + three others, which are subject to “subduction”, the loss and/or changing of the original semantic value).
