The conceptual field includes all the words in the vocabulary of a language, the new meanings that these words have acquired over time, and all the collocations they form together. Conceptual fields, which are in close relationship with semantics, reflect the characteristics of the culture of the language and express the world view of the society using that language by forming a linguistic field. In this study, the work the Viennese copy of the work called Kitâb-ı Güzîde, which was transferred from Arabic to Turkish in the Old Anatolian Turkish Period, was analysed in terms of conceptual fields in lexicology. It is tried to reveal how the conceptual fields contribute to the processing of the subject and theme. In addition, the words in Kitâb-ı Güzîde, which is a work of translation, were separated according to their origins and frequency of use, and the state of the vocabulary of the work written in the 14th century was revealed. The noun-derived words in the work were grouped according to the conceptual fields formed by synonyms / near synonyms, conceptual fields formed by words derived from the same root, conceptual fields formed by words belonging to the same field of knowledge, conceptual fields formed by common semantic units and conceptual fields formed by associative relations.
