请帮我把下面的文章翻译为英文书面语：古突厥语中的独角兽一词最早出现于唐代的泰山的汉文题记中文字形式qï at字面含义是气马。随着年代的下降该词的语音发生了变化。在回鹘时期写作ki atqatkatqï at。ki atqatkatqï at的意思并非汉语语境下的麒麟而是萨满教信仰文化中的神圣马匹气马与蒙古语单词hei mori气马的最初寓意相同。

The term "unicorn" in ancient Turkic language first appeared in the Han Chinese inscription on Mount Tai in the Tang Dynasty. It was written as "qï at" in written form, which literally means "spirit horse". As time went by, the pronunciation of this word changed. During the Khazar period, it was written as "ki at/qat/kat/qï at". The meaning of "ki at/qat/kat/qï at" is not the same as the Chinese context of "qilin" (unicorn), but refers to the sacred horse in shamanistic belief and culture called "spirit horse", which is similar to the original meaning of the Mongolian word "hei mori" (spirit horse)
