Did You Know?

English contains several sound homographs, all with distinct histories. For example, the sound that means "something heard" descends from Latin sonus ("sound"), whereas the sound that means "to measure the depth of water" traces to Old French sonde ("sounding line"). Another sound, however, is the contemporary form of Old English's gesund. Gesund is related to several words in other languages, such as Old Saxon gisund ("sound"), Old Frisian sund ("fresh, unharmed, healthy"), and Gothic swinths ("sound" or "healthy"). Another relative is Old High German's gisunt ("healthy"), which led to modern German's gesund, the root of gesundheit.

Origin of sound

Middle English, from Old English gesund; akin to Old High German gisunt healthy


First Known Use: 13th century

    Word Root of sound

    The Latin word sonāre, meaning “to make a noise,” gives us the root son. Words from the Latin sonāre have something to do with making noise. A sound is a noise made by someone or something. Something sonic uses the waves noises make as they travel through the air. A sonata is a musical piece in which only one instrument makes noise. To resound is to become filled with noise.
