In France, English is often perceived as a negative influence on the language in the eyes of purist institutions like the French Academy. Terminological commissions have been established to replace foreign expressions with French terminology that is regularly published in the Journal officiel de la République française. Although the Toubon Law of 1994 prescribes the use of this terminology in government publications, speakers are merely encouraged to do so. This article investigates the variation between English lexical borrowings and their prescribed equivalents in a large newspaper corpus containing articles from 2000 to 2017 in order to see whether formal written language complies with the purist recommendations. Time is treated with a new dynamic approach: the probability of using a prescribed term is estimated three years before and three years after official prescription. Fifty-four target terms are selected from the lexical fields of computer science, entertainment industry and telecommunication, including emblematic prescribed words such as courriel and mot-dièse. The analysis reveals that prescription is only effective when it follows already attested use. Furthermore, conservative newspapers show higher proportions of recommended terminology, especially as compared to newspapers specializing in technology.

开法语：法国报纸官方术语的语料库语言方法

在法国，在法国学院等纯粹主义机构的眼中，英语通常被视为对语言的负面影响。成立了术语委员会，用法语术语代替外国表达，这些术语定期在法兰西共和国官方杂志. 尽管 1994 年的 Toubon 法规定在政府出版物中使用该术语，但仅鼓励演讲者这样做。本文调查了包含 2000 年至 2017 年文章的大型报纸语料库中的英语词汇借用与其规定的对等物之间的差异，以了解正式的书面语言是否符合纯粹主义建议。时间用一种新的动态方法处理：使用规定期限的概率估计在正式规定之前三年和三年之后。54个目标词选自计算机科学、娱乐业和电信等词汇领域，包括标志性规定词，如信使和mot-dièse. 分析表明，处方只有在遵循已经证明的使用时才有效。此外，保守的报纸显示出更高比例的推荐术语，特别是与专门研究技术的报纸相比。
