In this work, prepared according to the principles of analytical grammar, word groups, sentence components, and sentence types used in Turkey Turkish have been examined in all their aspects in light of scientific knowledge and examples. In the first section, word groups; in the second section, sentence components and sentence types have been classified by dividing them into sub-groups according to their various characteristics, and these classifications have been supported with concept maps. Furthermore, for each concept discussed, the most widely accepted correct term has been used, and these concepts have been defined in a way that is comprehensive and exclusive. Subsequently, their sub-groups, if any, have been defined, and these have been examined down to the finest detail, with all their characteristics identified and exemplified. Thus, an original, easily understandable scientific reference source has been created to understand, learn, and teach the methods and principles of Turkish syntax, and this resource has been offered for the use of Turkish language researchers, instructors, learners, and users. Written in a plain and clear language, far from a heavy academic tone, the work serves as a reference source for Turkish language researchers, a textbook for the "Turkey Turkish Grammar-Word Groups and Sentence Structure" courses taught in university departments of Turkish Language and Literature, Turkish Language and Literature Education, and Turkish Language Education, a guide for Turkish Language and Literature and Turkish teachers working in primary and secondary education institutions, and an information source for language users.
