AlastoryoudaoicibaDictYouDict
in Greek tradition, son of Neleus, brother of Nestor, slain by Herakles. The name is perhaps literally "not to forget," from privative prefix a- "not" + root of lathein "to forget" (see Lethe), hence its use figuratively in sense of "an avenging spirit." Or else it might be connected with alaomai "to wander, roam," figuratively "to be distraught."
alb (n.)youdaoicibaDictYouDict
late Old English albe, from Late Latin alba (in tunica alba or vestis alba "white vestment"), fem. of albus "white," from PIE root *albho- "white" (cognates: Greek alphos "white leprosy," alphiton "barley meal;" Old High German albiz, Old English elfet "swan," literally "the white bird;" Old Church Slavonic and Russian lebedi, Polish łabędź "swan;" Hittite alpash "cloud").

AlbaniayoudaoicibaDictYouDict
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.
albatross (n.)youdaoicibaDictYouDict
1670s, probably from Spanish or Portuguese alcatraz "pelican" (16c.), perhaps derived from Arabic al-ghattas "sea eagle" [Barnhart]; or from Portuguese alcatruz "the bucket of a water wheel" [OED], from Arabic al-qadus "machine for drawing water, jar" (from Greek kados "jar"), in reference to the pelican's pouch (compare Arabic saqqa "pelican," literally "water carrier"). Either way, the spelling was influenced by Latin albus "white." The name was extended, through some mistake, by English sailors to a larger sea-bird (order Tubinares).

Albatrosses were considered good luck by sailors; figurative sense of "burden" (1936) is from Coleridge's "Rime of the Ancient Mariner" (1798) about the bad luck of a sailor who shoots an albatross and then is forced to wear its corpse as an indication that he, not the whole ship, offended against the bird. The prison-island of Alcatraz in San Francisco Bay is named for pelicans that roosted there.
