The process of specification of the social and, in particular, the process of demarcation between the social and the legal spheres in Early Modern European intellectual discourse exhibited both general regularities and elements contingent on the regional specificity of intellectual traditions and institutional practices. In the article, the author examines the Scottish version of this process, with the lexicography of the Scottish civil lawyer Sir John Skene (1549–1617) “De Verborum Significatione” serving as a case in point. The analysis of the social concepts included in the lexicography demonstrates that the heterogeneity of the genesis of strata and groups within the Scottish nobility, as observed by contemporaries, precluded the establishment of a hierarchy of noble titles and dignities within the Scottish kingdom. Consequently, reflection on the nobility as a social phenomenon was also prevented. Conversely, the ascendancy of civil law, with its rigorously delineated subject matter and enduring lexical apparatus, fostered the elaboration of the legal domain. However, this process also impeded the differentiation between the legal and the social. The author demonstrates that numerous concepts that would subsequently be imbued with particular social connotations within the Scottish intellectual tradition during the seventeenth century were nevertheless still regarded as an intrinsic component of the legal framework within the community of the kingdom. When referenced in the Scottish laws and parliamentary acts examined by Skene, these concepts were closely associated with legal privileges, judicial procedure, or the distinctive characteristics of property relations.
