banjo: [18] The origins of banjo are uncertain, but its likeliest source seems to be bandore, the name of a 16th-century stringed instrument similar to the lute. It has been argued that in the speech of Southern US blacks, amongst whom the banjo originated, bandore became banjo, perhaps under the influence of mbanza, a term for a similar instrument in the Kimbundu language of Northern Angola (although it might be more plausible to suggest that mbanza is the immediate source, altered by English-speakers more familiar with bandore). Bandore itself appears to be a variant of pandore or pandora, which comes from Greek pandoura ‘three-stringed lute’.

A more farreaching modification produced mandore, likewise a term for a lutelike instrument. The Italian version of the word, mandola, is familiar in English from its diminutive form, which has given us mandolin [18].

"of or pertaining to blacks on the sea-islands of Georgia and South Carolina," 1739 (first attested as a male slave's proper name), of uncertain origin. Early 19c. folk etymology made it a shortening of Angola (homeland of many slaves) or traced it to a West African tribal group called the Golas.
