hamster: [17] The hamster is a native of western Asia and southeastern Europe, and its English name is of Slavic origin. In Old Slavic it was called chomestoru, and it appears that at some point in the past an ancestor of this was borrowed into Germanic. Old High German had hamustro, which became modern German hamster, source of the English word. In the 18th century the animal was also called the German rat.

The older English name for it was German rat.
hamstring (v.)youdaoicibaDictYouDict
1640s, "to disable, render useless," a figurative verbal extension from hamstring (n.) "tendon at the back of the knee." Cutting this would render a person or animal lame. Literal sense of the verb is attested from 1670s. Since it is a verb from a noun-noun compound, hamstrung as a past participle is technically incorrect.
[I]n hamstring, -string is not the verb string; we do not string the ham, but do something to the tendon called the hamstring; the verb, that is, is made not from the two words ham & string, but from the noun hamstring. It must therefore make hamstringed. [Fowler]
