The term MOISTENS IN THE MORN can be solved by the four-letter word DEWS. Dew is a type of condensation that forms on surfaces in the morning due to the cooling of the air overnight. It is composed of tiny droplets of water that form when the temperature of the surface drops below the dew point, the temperature at which the air is saturated with water vapor. Dew is an important source of moisture for plants and animals, and it is often used as a metaphor for freshness and renewal.
