Sierra Leone 
West African nation, literally "lion mountains," from Spanish sierra "mountain range" (see sierra) + leon "lion" (see lion). Attested from mid-15c. in Portuguese explorers' accounts, and a very early explanation of the name derives it from the "roaring" of thunder in the mountains. Related: Sierra Leonean.

mandrill (n.)

"the largest, most hideous, and most ferocious of the baboons" [OED], 1744, perhaps ultimately from a West African language, but formed into the English components man (n.) + drill (n.4) "baboon," which is of West African origin. The earliest reference reports the name is what the animal was "called by the white men in this country [Sierra Leone], but why it is so called I know not, nor did I ever hear of the Name before, neither can those who call them so tell, except it be for their near Resemblance of a human Creature, though nothing at all like an Ape." [William Smith, "A New Voyage to Guinea"].  French mandrill, Spanish mandril seem to be from English.

Granada 
Moorish kingdom, after 1492 a Spanish province, named for its city, which was founded in 8c. by the Arabs on the site of Roman Illiberis. The name is said to be from Latin granatum "pomegranate," either from fruit grown in the region or from some fancied resemblance. Others connect the name to Moorish karnattah, said to mean "hill of strangers." The Roman name is said to be Iberian and represent cognates of Basque hiri "town" + berri "new," and it survives in the name of the surrounding Sierra Elvira. Related: Granadine.
