What does murky mean?
Murky describes something that is dark, clouded, or not fully visible, especially water. The word also applies figuratively to information, motives, histories, and accounts that are vague, confusing, or ethically unclear. In phrases such as murky waters and a murky past, it conveys an impression of concealment and uncertainty rather than merely a lack of detail. Its strongest figurative sense often suggests that something is deliberately obscured or that its nature is questionable. Murky can sound more evocative and literary than simply saying that something is unclear, while remaining common in news, political, and legal writing. It is especially useful when describing conditions in which facts or moral judgments cannot easily be seen.
Dark or unclear, especially because of cloudiness, sediment, or insufficient light; vague or morally ambiguous.
"The lake was murky, and the submerged rocks were difficult to distinguish."
The figurative senses are common in discussion of evidence, motives, histories, and ethical conduct.
To become murky or to make something murky.
"The wine murkied as it sat in the cellar."
