Etymology

Origin of noisy

First recorded in 1685–95; noise + -y 1

Explanation

Anything noisy is loud. Your noisy party probably won't go over too well with your downstairs neighbors — especially if it's late on a Tuesday night and they have a sleeping baby. Something that makes loud sounds or is generally rowdy and boisterous can be called noisy. A noisy bar is a harder place to have a conversation than a quiet restaurant, but a noisy dance party tends to me much more fun than a solemn tea party with your cranky grandparents. Before there was noisy, around the late 1600s, the adjective was noiseful. Curiously, experts guess that the Latin root of noisy and noise is nausea, "seasickness."
