The book “Rucavas sievu stāsti” (Rucava Women’s Stories, 2023) reflects the intangible cultural heritage of the Rucava cultural space, revealing various kinds of traditional knowledge and craft skills. It is written in the modern Rucava subdialect, so there are parallel variations in the use of words and inflexions. It means that both literary forms and dialectal features are used. The article aims to clarify the morphological characteristics of nouns, pronouns and number in the book “Rucava Women’s Stories”. The object of the study is 50 stories, which were evaluated for the morphological means used to depict the contemporary Rucava subdialect. The main research methods used in the study are analytical and comparative methods. Various examples of inflective word classes were extracted from the linguistic material. The comparative method was used to identify the intensity of the use of literary language forms and dialectal features, to collect the data on which morphological language means dominate in the texts, and to find out the proportions of language means. The study concludes that the proportions of morphological forms of the subdialect in relation to the literary language are different. There are cases when the use of certain archaic forms is predominant over the literary language variant, e.g. ē-stems of the nouns, the indeclinable pronouns mana, sava. However, there are cases where an ancient morphological or inflectional form is not used in the text when reproducing the language of a modern subdialect. The different proportions of archaic forms in relation to literary language, their density, and predominance or loss in contemporary spoken and written language may be related to the particular author’s sense of subdialect, description of an event, and representation of an experience. The use of dialectal features in the book creates a lively and joyful atmosphere, revealing the knowledge and skills of Rucava women in various crafts.
