ivyyoudaoicibaDictYouDict[ivy 词源字典]
ivy: [OE] Ivy has been traced back to a prehistoric Germanic *ibakhs, which also lies behind modern German efeu and Dutch eilof. This has been linked by some etymologists with Latin ibex ‘mountain goat’ (itself acquired by English in the 17th century), the semantic connection being ‘climber’. The expression Ivy League, denoting the eight old-established and prestigious universities of the northeastern USA (Brown, Columbia, Cornell, Dartmouth, Harvard, Pennsylvania, Princeton, and Yale), was inspired by the idea of ancient ivy-covered walls. It dates from the 1930s.

Samoyed (n.)youdaoicibaDictYouDict
Siberian Mongolian people, 1580s, from Russian samoyed (11c.), traditionally literally "self-eaters," i.e. "cannibals" (the first element cognate with same, the second with eat), but this might be Russian folk etymology of a native name:
The common Russian etymology of the name Samoyed, meaning "self-eater," deepened the Russians' already exotic image of far-northerners. The most probable linguistic origin of Samoyed, however, is from the Saami -- saam-edne, "land of the people" [Andrei V. Golovnev and Gail Osherenko, "Siberian Survival: The Nenets and Their Story," Cornell University, 1999]
Which would make the name a variant of Suomi "Finn." The native name is Nenets. As the name of a type of dog (once used as a working dog in the Arctic) it is attested from 1889.
