The formation or appearance of dew, particularly the time in the evening or early morning when dew begins to form on surfaces.
From 'dew' (Old English daug) + 'fall' (Old English feallan). The compound describes the phenomenon or moment when dew settles on the landscape, similar to how 'rainfall' describes falling rain.
Medieval farmers used 'dewfall' like we use weather apps—they watched it to predict frost and plan their work, because heavy dewfall meant a cold night was coming and frost might damage crops!
