<注釋>Although Saint Nick uses reins on his reindeerand reindeer are used to pull sleds in Lapland and northern Siberia,the wordreindeer has nothing to do with reins. The element-deer is indeed our word deer, but therein- part is borrowed from another language, specifically from the Scandinavian languages spoken by the chiefly Danish and Norwegian invaders and settlers of England from the 9th to the th century.Even though the Old Icelandic language in which much of Old Norse literature is written is not the same variety of Old Norse spoken by these settlers of England,it is close enough to give us an idea of the words that were borrowed into English.Thus we can cite the Old Icelandic wordhreinn, which means .reindeer,. as the source of the first part of the English word. The wordreindeer is first recorded in Middle English in a work composed before 400.
儘管聖誕老人在他的馴鹿身上用韁繩，且馴鹿過去在拉普蘭和西伯利亞北部曾被用來拖拉雪撬，reindeer 這個字卻和韁繩沒有任何關係。 構詞元素-deer 確實是我們的單詞 deer， 但是rein 這一部分是從其他語言中借用過來的， 特別是主要從丹麥和挪威的入侵者及9世紀到世紀列英格蘭定居者說的斯堪的納維亞語借用的。儘管許多古代北歐文學都使用的古冰島語與這些到英格蘭定居的人所說的古代北歐語並不是同一變體，但它對於我們認識借進英文的辭彙也是足夠接近的。這樣，我們便可以引用意為.馴鹿.的古冰島語hreinn 來作為英文單詞第一部分的來源。 Reindeer 最早在400年以前所著的一部作品中以中古英文記錄下來
