guitar: [17] The Greek kithárā was a stringed musical instrument of the lyre family, which has bequeathed its name to a variety of successors. Via Latin cithara came English citole [14], a medieval stringed instrument, and German zither (borrowed by English in the 19th century), while Arabic took it over as qītār and passed it on to Spanish as guitarra.

French adopted it in the form guitare (which eventually superseded the earlier guiterne), and it eventually reached English. (The history of guiterne, incidentally, is not entirely clear, although it is obviously a member of the kithárā family. English acquired it as gittern [14], applied to an early form of guitar, and it seems to have been blended with Latin cithara to produce English cithern or cittern [16], the name of a plucked stringed instrument of Renaissance times.)

guitar (n.)youdaoicibaDictYouDict
lute-like musical instrument, 1620s, from French guitare, which was altered by Spanish and Provençal forms from Old French guiterre, earlier guiterne, from Latin cithara, from Greek kithara "cithara," a triangular seven-stringed musical instrument related to the lyre, perhaps from Persian sihtar (see sitar). The name reached English several times, including giterne (early 14c., from Old French), in reference to various stringed, guitar-like instruments; the modern word is also directly from Spanish guitarra (14c.), which ultimately is from the Greek. The Arabic word is perhaps from Spanish or Greek, though often the relationship is said to be the reverse. The modern guitar is one of a large class of instruments used in all countries and ages but particularly popular in Spain and periodically so in France and England. Other 17c, forms of the word in English include guittara, guitarra, gittar, and guitarre. Compare zither, gittern.
