camel: [OE] Naturally enough, camel is of Semitic origin: Hebrew has gāmāl, for example, and Arabic jamal. It was a relative of these that was the source of Greek kámēlos, which passed via Latin camēlus into English as early as the mid 10th century. (It replaced a previous Old English olfend, a word – shared by other early Germanic languages – apparently based on the misconception that a camel was an elephant.)
[camel etymology, camel origin, 英语词源]
camel (n.)youdaoicibaDictYouDict
Old English camel, perhaps via Old North French camel (Old French chamel, Modern French chameau), from Latin camelus, from Greek kamelos, from Hebrew or Phoenician gamal, perhaps related to Arabic jamala "to bear."

Another Old English word for the beast was olfend, apparently based on confusion of camels with elephants in a place and time when both were known only from travelers' vague descriptions. The Arabian have one hump (the lighter variety is the dromedary); the Bactrian have two.
