What does muggier mean?
Muggier is the comparative form of the adjective muggy. It describes something that is becoming or is more damp, humid, close, or oppressive, particularly in warm, still weather or in crowded, poorly ventilated spaces. The word is commonly applied to afternoons, weather, rooms, trains, and other situations associated with trapped moisture and stale air. “Muggier” often implies increasing discomfort rather than simply describing the presence of dampness: the atmosphere feels muggier, the day is muggier, or the room grows muggier. Its tone is informal but widely understood, making it especially useful in everyday descriptions of weather and physical surroundings. Because it is a comparative form, it normally appears with “than” or with words such as “get” and “grow.”
