Etymology -
The word accent derives via French from the Latin accentus, song added to speech (from ad-, to + cantus, a singing).
Note: The Latin word was coined as a loan translation of the Greek prosoidia, which purportedly described the pitch scheme used in Greek verse.

Oxford English Dictionary -
Its first citation in sense (1) is from 1600:
"Your accent is something finer, then you could purchase in so remoued a dwelling."
(Shakespeare, As You Like it, iii. ii. 359)
