Materials for a historical dictionary of New Persian loanwords in Old Anatolian and Ottoman Turkish from the 13th to the 16th century. The work is a collection of New Persian loanwords in Old Anatolian and early Ottoman Turkish. It consists of nearly 2000 items. The vocabulary presented here has been extracted from various sources originally written in the Arabic script, in present times transcribed into the Latin script and edited by modern scholars.

"Commenced in the 1970s, the study of Persian influence on Ottoman Turkish vocabulary is still far from, at a least a provisional, conclusion. [The author] supplies us with a multitude of data, sorted alphabetically and hence easily accessible, and dated, hence providing the information about the chronology of forms and meanings, perhaps the most essential kind of information in the Ottoman studies today. Phonetic and semantic attestations constitute the main body of the work. They were excerpted from philological sources, where they lay scattered till now, and so de facto almost impossible to find for the researcher."
