alb (n.)
late Old English albe "white linen robe" worn by priests, converts, etc., from Late Latin alba (in tunica alba or vestis alba "white vestment"), fem. of albus "white," from PIE root *albho- "white" (source also of 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").

sanderling (n.)

"three-toed sandpipe," a wading bird (Crocethia alba) found on sandy beaches worldwide, c. 1600, probably from sand (n.) + diminutive suffix -ling, but OED suggests possible derivation from Old English *sand-yrðling, with second element yrðling "plowman" (literally "earthling"), which is at least charming. Century Dictionary points to sandling "sand-eel" (mid-15c.), also, later, the name of a small, flat fish.

Albion 

ancient name of England, attested in Old English, from Latin, sometimes said to be from the non-Indo-European base *alb "mountain," which also is suggested as the source of Latin Alpes "Alps," Albania, and Alba, an Irish name for "Scotland." But more likely from Latin albus "white" (see alb), which would be an apt description of the chalk cliffs of the island's southern coast.

Breoton is garsecges ealond, ðæt wæs iu geara Albion haten. [translation of Bede's "Historia Ecclesiastica Gentis Anglorum," c. 900 C.E.]

Perfidious Albion, a reference to the supposedly treacherous policies of Britain when dealing with foreign powers, translates French rhetorical phrase la perfide Albion, said to have been in use since 16c. but popularized by Napoleon in the recruiting drive of 1813.

magnesia (n.)

late 14c., in alchemy, "one of the two main ingredients of the philosopher's stone," from Medieval Latin magnesia, from Greek (he) Magnesia (lithos) "the lodestone," literally "(the) Magnesian (stone)," a mineral said to have been brought from Magnesia, the region in Thessaly, which is said to be named for the native people name Magnetes, which is of unknown origin.

The ancient word, in this sense, has evolved into magnet. But in ancient times the same word, magnes, was used of lodestone as well as of a mineral commonly used in bleaching glass (modern pyrolusite, or manganese dioxide).

In the Middle Ages there was some attempt to distinguish lodestone as magnes (masc.) and pyrolusite as magnesia (fem.). Meanwhile, in 18c., a white powder (magnesium carbonate) used as a cosmetic and toothpaste was sold in Rome as magnesia alba ("white magnesia").

It was from this last, in 1808, that Davy isolated magnesium. He wanted to call it magnium, to stay as far as possible from the confused word magnesia, but the name was adopted in the form magnesium. Meanwhile from 16c. the other name of pyrolusite had been corrupted to manganese, and when, in 1774, a new element was isolated from it, it came to be called manganese.

Magnesia in its main modern sense of "magnesium oxide" (1755) is perhaps an independent formation from Modern Latin magnes carneus "flesh-magnet" (c. 1550), so called because it adheres strongly to the lips.

blond (adj.)

of hair, "of a golden or light golden-brown color," late 15c., from Old French blont "fair, blond" (12c.), from the same source as Medieval Latin blundus "yellow," but of uncertain origin. Perhaps from Frankish *blund or another Germanic source (compare Dutch, German, Danish blond).

If it is a Germanic word, it is possibly related to Old English blonden-feax "gray-haired," from blondan, blandan "to mix" (see blend (v.)). According to Littré, the original sense of the French word was "a colour midway between golden and light chestnut," which might account for the notion of "mixed." [But Century Dictionary finds this "hardly probable."]

Old English beblonden meant "dyed," so it is also possible that the root meaning of blonde, if it is Germanic, may be "dyed," as ancient Teutonic warriors were noted for dying their hair. Du Cange, however, writes that blundus was a vulgar pronunciation of Latin flavus "yellow." Another guess (discounted by German etymologists), is that it represents a Vulgar Latin *albundus, from alba "white."

The word was reintroduced into English 17c. from French, and was until recently still felt as French, hence blonde (with French feminine ending) for females. Italian biondo, Spanish blondo, Old Provençal blon are said to be ultimately of Germanic origin.

Fair hair was much esteemed by both the Greeks and Romans, and so they not only dyed and gold-dusted theirs ..., but also went so far as to gild the hair of their statues, as notably those of Venus de Medici and Apollo. In the time of Ovid (A.U.C. 711) much fair hair was imported from Germany, by the Romans, as it was considered quite the fashionable color. Those Roman ladies who did not choose to wear wigs of this hue, were accustomed to powder theirs freely with gold dust, so as to give it the fashionable yellow tint. [C. Henry Leonard, "The Hair," 1879]
