AlbaniayoudaoicibaDictYouDict[Albania 词源字典]
Medieval Latin name of the country called by its inhabitants Shqipëri (literally "land of eagles," from shqiponje "eagle"), from Medieval Greek Albania, possibly from a pre-IE word *alb "hill" (also proposed as the source of Alps) or from the PIE root *albho- "white" (see alb). Roman Albania was a land by the Caspian Sea (modern Daghestan); in English Albania was occasionally also a name for Scotland.[Albania etymology, Albania origin, 英语词源]
Caucasian (adj.)youdaoicibaDictYouDict
1807, from Caucasus Mountains, between the Black and Caspian seas; applied to the "white" race 1795 (in German) by German anthropologist Johann Blumenbach, because its supposed ancestral homeland lay there; since abandoned as a historical/anthropological term. (See Aryan).
HyrcaniayoudaoicibaDictYouDict
ancient region southeast of the Caspian Sea, from Greek Hyrkania, said to be from an Indo-European *verkana "country of wolves" [Zonn, I., et al., "The Caspian Sea Encyclopedia," 2010]
TartaryoudaoicibaDictYouDict
mid-14c. (implied in Tartary, "the land of the Tartars"), from Medieval Latin Tartarus, from Persian Tatar, first used 13c. in reference to the hordes of Ghengis Khan (1202-1227), said to be ultimately from Tata, a name of the Mongols for themselves. Form in European languages probably influenced by Latin Tartarus "hell" (e.g. letter of St. Louis of France, 1270: "In the present danger of the Tartars either we shall push them back into the Tartarus whence they are come, or they will bring us all into heaven").

The historical word for what now are called in ethnological works Tatars. A Turkic people, their native region was east of the Caspian Sea. Ghengis' horde was a mix of Tatars, Mongols, Turks, etc. Used figuratively for "savage, rough, irascible person" (1660s). To catch a Tartar "get hold of what cannot be controlled" is recorded from 1660s; original sense not preserved, but probably from some military story similar to the old battlefield joke:
Irish soldier (shouting from within the brush): I've captured one of the enemy.
Captain: Excellent! Bring him here.
Soldier: He won't come.
Captain: Well, then, you come here.
Soldier: I would, but he won't let me.
Among the adjectival forms that have been used are Tartarian (16c.), Tartarous (Ben Jonson), Tartarean (17c.); Byron's Tartarly (1821) is a nonce-word (but a good one). Tartar sauce is first recorded 1855, from French sauce tartare.
wolf (n.)youdaoicibaDictYouDict
Old English wulf "wolf, wolfish person, devil," from Proto-Germanic *wulfaz (cognates: Old Saxon wulf, Old Norse ulfr, Old Frisian, Dutch, Old High German, German wolf, Gothic wulfs), from PIE root *wlkwo- "wolf" (cognates: Sanskrit vrkas, Avestan vehrka-; Albanian ul'k; Old Church Slavonic vluku; Russian volcica; Lithuanian vilkas "wolf;" Old Persian Varkana- "Hyrcania," district southeast of the Caspian Sea, literally "wolf-land;" probably also Greek lykos, Latin lupus).
This manne can litle skyl ... to saue himself harmlesse from the perilous accidentes of this world, keping ye wulf from the doore (as they cal it). ["The Institution of a Gentleman," 1555]
Probably extinct in England from the end of the 15th century; in Scotland from the early 18th. Wolves as a symbol of lust are ancient, such as Roman slang lupa "whore," literally "she-wolf" (preserved in Spanish loba, Italian lupa, French louve). The equation of "wolf" and "prostitute, sexually voracious female" persisted into 12c., but by Elizabethan times wolves had become primarily symbolic of male lust. The specific use of wolf for "sexually aggressive male" first recorded 1847; wolf-whistle attested by 1945, American English, at first associated with sailors. The image of a wolf in sheep's skin is attested from c. 1400. See here for a discussion of "wolf" in Indo-European history. The wolf-spider so called for prowling and leaping on its prey rather than waiting in a web.
