What does miasmal mean?
Miasmal is a formal, literary adjective describing something associated with miasma: an unwholesome atmosphere, a pervasive sense of corruption, or an influence that seems to poison everything around it. In literal contexts, it evokes foul, stagnant, or polluted air, although the word is often used metaphorically to characterize institutions, atmospheres, or periods of history marked by decay and moral corruption. For example, writers may describe a decaying city as miasmal or describe the secrecy surrounding a scandal as creating a miasmal atmosphere. The adjective is less common than the noun miasma and carries a conspicuously negative tone. It can apply to physical conditions, but its figurative use often suggests something difficult to identify or remove. The word is valuable because it compresses both sensory revulsion and the idea of hidden corruption into a vivid, memorable description.

Miasmal reaches back to ancient Greek, where its root meant pollution or moral taint—a meaning that still gives the word its choking sense.
