spinet: [17] A spinet is a sort of small harpsichord. English acquired the term via early modern French espinette from Italian spinetta, and one version of its origin is that it came from the name of one Giovanni Spinetti, a Venetian who supposedly invented the instrument at the beginning of the 16th century. A more prosaic story is that it was a diminutive form of spina ‘thorn’ (a relative of English spine), the allusion being to the plucking of the strings with thornlike quills.
