Origin

The character 湖 combines water (shown by the 氵 component on the left, which is a simplified form of the water radical) with 胡 on the right, which serves as a sound hint for the pronunciation "こ" rather than contributing a meaning. The water radical indicates this character refers to something liquid or aquatic, while the sound component helps readers know how to pronounce it. Together they create a character meaning lake — a large body of water — with the visual element immediately suggesting its watery nature.
