What does phlegmy mean?
Phlegmy is an adjective describing someone or something affected by phlegm, the thick mucus produced by the respiratory system. The word commonly refers to a cough, a congested or mucus-filled chest, a blocked-up voice, or difficult, wet-sounding breathing. It is especially associated with colds, bronchitis, and similar respiratory conditions, although it is sometimes used more generally for a person's conspicuous production of mucus. The term is primarily descriptive rather than technical and can sound mildly unpleasant or disapproving, especially when applied to a noisy cough in public. Understanding phlegmy helps distinguish a physical symptom from the similarly sounding word phlegmatic, which concerns temperament rather than bodily congestion. It is also distinct from merely “wet,” since phlegmy specifically implies mucus produced by the respiratory tract.
adjectiveHaving or characterized by a lot of phlegm, especially in the throat or lungs; producing mucus when coughing or speaking.
- Having or producing a large amount of phlegm or mucus, especially in the throat, chest, or lungs.
"She became hoarse and phlegmy after catching a cold."
"The child had a deep, phlegmy cough that kept echoing through the house."
"His voice became phlegmy as he tried to speak over the noisy meeting."
A phlegmy cough is often more sound than substance: the word describes the body's production of mucus, not a personality.

Where does phlegmy come from?
Phlegmy derives from phlegm, which comes through Old French from Latin phlegma, a term associated with Greek phlegma, meaning mucus or bodily fluid. The adjective developed from the same source as phlegmatic, a word that originally referred to bodily humours and later came to describe a calm or unemotional temperament. The modern medical sense of phlegmy follows the older, literal sense of phlegm as mucus from the respiratory system.
