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 Middle French sonde ("sounding line"). Another sound, as in "of sound mind and body," 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.
