luthier (n.)

stringed musical instrument, late 13c., from Old French lut, leut (Modern French luth), from Old Provençal laut, a misdivision of Arabic al-'ud, the Arabian lute, literally "the wood" (source of Medieval Latin lutana, Spanish laud, Portuguese alaude, Italian liuto), where al is the definite article.

Dutch luit, German Laute, Danish luth are from Romanic. A player is a luter (Middle English), a lutist (1620s) or a lutanist (c. 1600, from Medieval Latin lutanista).
