This article analyses the role of linguistic skills in the process of defining professional classifications in Spain during 1919–1980. The aim is to determine the social evaluation of the skills involved. To retrace the classifications, a total of 114 official documents were examined, establishing a chronological division into three major stages: 1920–1940, 1940–1960 and 1960–1980. The first period (1920–1940) shows efforts toward the initial objectification of working conditions and salary scales, revealing social prejudices and tacit conventions shaping the employment hierarchy, while the second one (1940–1960) indicates the extent to which office work stood out over manual work. Finally, the third stage (1960–1980) shows processes of language rationalisation, which entailed attempts to standardise positions based on required skill sets.

劳动力市场合理化过程中的语言：横跨二十世纪西班牙的社会历史方法

本文分析了语言技能在 1919 年至 1980 年期间在西班牙定义专业分类过程中的作用。目的是确定对所涉及技能的社会评价。为追溯分类，共审查了 114 份官方文件，将其按时间顺序划分为三个主要阶段：1920-1940 年、1940-1960 年和 1960-1980 年。第一个时期（1920-1940）显示了对工作条件和薪资等级的初步客观化的努力，揭示了塑造就业等级的社会偏见和默契，而第二个时期（1940-1960）表明了办公室工作的突出程度在手动工作。最后，第三阶段（1960-1980）展示了语言合理化的过程，这需要尝试根据所需的技能组合来标准化职位。
