Language is a vital part of human connection. All people need language in order to build relations with other people. Besides this, language encodes culture and provides the means through which culture is shared and passed from one generation to the next. In this sense, language is the basis of social and communicative ability. Communication is the transmission of signals or messages through verbal or nonverbal linguistic signs. Throughout this process, effective use of cultural signs positively affects the communication cycle. Especially, the use of texts including rich cultural elements helps the learner understand the nuances of meaning. With rich motifs, fantastic fiction, elements of curiosity and rich cultural content, Dede Korkut stories are in this sense among the rare works that are suitable for in the field of teaching Turkish as a foreign language. To this end, it is of great importance to find cultural patterns embedded in Dede Korkut stories and take advantage of these texts in teaching Turkish as a foreign language. The study aims to find cultural patterns embedded in Dede Korkut stories and to classify the vocabulary units, i.e., building blocks of these cultural patterns. Research data has been collected through using document analysis method.
