The orthography of the name Ankara has varied over the ages. It has been identified with the Hittite cult center ''Ankuwaš'',  although this remains a matter of debate. In classical antiquity and during the medieval period, the city was known as ''Ánkyra'' (,  "anchor") in Greek and ''Ancyra'' in Latin; the Galatian Celtic name was probably a similar variant. Following its annexation by the Seljuk Turks in 1073, the city became known in many European languages as ''Angora''; it was also known in Ottoman Turkish as ''Engürü''. The form "Angora" is preserved in the names of breeds of many different kinds of animals, and in the names of several locations in the US (see Angora).
