Definition and Meaning of Moody
Moody is an adjective used to describe someone whose mood or behavior changes often, especially when those changes involve being unhappy, annoyed, quiet, or difficult to read.
For example:
He has been moody all afternoon.
This suggests that his mood or behavior has not been steady.
The word can also describe a dark, emotional, or atmospheric quality in things such as moody music, moody lighting, or moody weather.
A Note About Synonym Accuracy
The word moody has a broad meaning, so its alternatives are not all interchangeable. Temperamental is useful when the focus is on changing moods, while irritable focuses on being easily annoyed. Sullen and sulky describe quiet unhappiness or anger. Words such as gloomy, glum, and melancholic focus more on sadness.
This distinction matters because choosing a synonym based only on a word list can change the meaning of a sentence.
