accompanist

The word 'accompanist' is built upon the verb 'accompany', which entered English from Old French 'acompaignier', meaning "to go with as a companion." This French term itself derives from the Vulgar Latin 'accompaniare', a combination of 'ad-' (to) and 'companionem' (companion, literally "one who shares bread"). The agent suffix '-ist', of Greek origin via Latin, was later appended to create a noun specifically denoting a person whose role is to musically "go with" a soloist. Thus, the term's logic moves from the general concept of companionship to the specialized professional role of providing musical support.
