While evidence suggests that eh initially may have been considered as an onomatopoeic sound, the earliest uses of eh found so far, date back to Early Modern English in 1662, but first mentions of it are found in Middle English. In 1707, it was first used in a play, functioning "to create or confirm agreement." Later, in 1773, its earliest quotation, s.v. "eh" was in a play by Irish playwright Oliver Goldsmith.
