What does moisten mean?
To moisten is to make something slightly wet, or to become slightly wet oneself. The word is often used when a surface, material, or substance needs moisture rather than a thorough soaking: one may moisten soil, a cloth, bread, or dough. It can also describe a person's eyes moistening with tears, or a surface becoming damp. In this sense, “moisten” is more precise and often gentler than “wet,” which can suggest a larger amount of liquid or a more forceful action. The word appears in practical, literary, and figurative contexts, including descriptions of cooking, gardening, weather, and emotional reactions.
