Synonym discussion

Sense: adjective/1

Dark is the most general word for a space with little or no light. Dim describes a space where there is some light, but not enough to see clearly — a dim room still lets you make out shapes, while a dark room may not. Gloomy adds a feeling of sadness or depression to the lack of light: a gloomy day is both dark and cheerless. Shadowy highlights the presence of dark shapes or cast shadows rather than overall darkness — a shadowy corner may have light elsewhere in the room. Murky is used for darkness that is thick, cloudy, or hard to see through, especially in water or air: a murky pond is dark and unclear. Use dark for general lack of light, dim for reduced visibility, gloomy for emotional tone, shadowy for partial darkness with visible shapes, and murky for darkness combined with cloudiness or confusion.

Etymology

Old EnglishMiddle EnglishModern English

Dark comes from Old English deorc, meaning 'without light, gloomy, sad.' It is related to Old High German tarchanjan ('to hide, conceal'), which connects to the sense of secrecy. The word has been used since the 1200s to describe both physical darkness and emotional or moral gloom. The verb darken appeared in the 1300s, and the noun darkness became common in Middle English religious texts to describe the absence of divine light.
