The article is based on a PhD research on the forms of address in Dutch and in Polish from the 17th until the 20th century. The article reflects the analysis of Dutch nominal forms of address in the 18th century. The nominal forms of address are widely represented in the language besides pronominal forms. They also combine with the latter according to more or less established rules. The nominal forms that are analysed come from Dutch plays. The division into nominal classes such as name, last name and title reveals the distribution of nominal forms of address in Dutch in a period given.
