TEKİN
In Old Turkic, tegin was the stuff of inscriptions and dynasties, carved into the 8th-century Orkhon Inscriptions beside names like Kül Tegin. It meant prince, heir, royal son. However, Mahmud al-Kaşgarî, the first lexicographer of the Turkish language, reminds us that these gilded offspring referred to themselves as “kul,” or servant, when addressing their father in a ritual display of humility, claiming that “tekin” meant “humble servant.”
