The paper presents and investigates the incidence of nominal clauses in spoken and written English. The focus
is placed on the frequency of occurrence and the range of subordinators that introduce this type of subordinate
clause. It applies comparative analysis to define differences in the use of nominal clauses within a small-size corpus
comprising of texts that represent spoken and written English. The most common nominal clauses are interrogative
clauses and (nominal) that-clauses. Nominal clauses are formed when an interrogative or nominal-that introduces
a clause by serving as the subject of the clause or preceding the clause in order to serve a noun role in another
structure. In short, Nominal Clauses can serve any nominal role: subject, direct object, subject complement, object
of the preposition, object complement, indirect object, adjective complement, or appositive. A quantitative research
method is used to determine the frequency of occurrence of nominal clauses and particular subordinators in the
selected registers in English, namely conversation (interviews-IW) and fiction (FC). The purpose of the study is
to find out potential differences in the employment of nominal clauses in different media of language production.
Based on quantitative analysis of nominal clauses in the different texts of spoken and written discourse, the paper
presents frequency counts and interprets them as indicative of the character of the discourse
