Intertextuality in the research of the language of science is the analysis of various written indications and language-specific formulations; thus, it is an important part of the study of the scientific style of each language. The aim of this study is to investigate and describe the specifics of intertextuality in linguistic papers in Latvian, focusing on (1) types of citations, (2) the integration of citations in the text, and (3) the linguistic means used for introducing the citation. Based on the reference and empirical material content analysis and the calculation of its quantitative parameters, the study of the verb forms and semantic classification used for the citation application in integrated and non-integrated citations has been carried out on the basis of excerpted citations and paraphrases found in the texts. The results obtained show a wide variety of uses and forms of references. The corpus created for this study consists of 30 linguistics papers selected according to certain criteria; the average number of cited works per article is 30, and the average number of references is 42, but their variation is significant – from 4 to 147 references per article. The predominant type of citation is paraphrasing – 85% of all citations. Different subtypes of citations have been identified for both integrated and non-integrated citations. Diversity can be observed in the range of verbs selected for the citation and their forms of use. 246 excerpted examples show 76 different meanings of verbs in the simple present or simple past, in the form of the continuous present with or without an auxiliary verb, verbs that impose a requirement, in passive forms of the continuous and simple present, as well as in the broader syntactic constructions together with a participle clause. The semantics of the verbs used for the citation indicate various activities; they can inform, define, express an opinion, evaluate, point to the classification or focus on the insights used. The obtained results confirm the complex nature of intertextuality and allow us to conclude the need for further research in relation to the analysis of citation functions in separate parts of scientific articles, as well as in comparison with the genres of other scientific texts and/or texts of other fields. The results obtained in the study can be integrated into methodological instructions for different target groups.
