Word of the Day: PHLEGM
Pronunciation:UK /flem/ US /flem/
Meaning
Phlegm is a thick mucus produced in the respiratory system, especially during illness, infections, or irritation of the throat and lungs.
It is often coughed up from the chest and is associated with colds, flu, bronchitis, and other respiratory conditions.
In older medical theory, the word also had a broader historical meaning related to bodily humours, but in modern usage it refers specifically to respiratory mucus.
Example for daily usage
- He had a bad cold and was coughing up phlegm.
- The doctor said the infection was causing excess phlegm in the lungs.
Origin and history
The word phlegm comes from the Greek 'phlegma', meaning inflammation or bodily fluid produced by heat. It entered Latin as phlegma and later passed into Old French before entering English.
In ancient Greek medicine, phlegm was one of the four bodily humours believed to influence human health and temperament. People with an excess of phlegm were thought to have a calm or sluggish personality, which is why the word also historically influenced the term "phlegmatic."
Modern medicine no longer uses the humour theory, but the word phlegm has remained in use to describe respiratory mucus.
Cultural significance and modern usage
Today, phlegm is primarily used in medical and everyday health contexts. It is a common term in healthcare discussions, especially when describing symptoms of respiratory infections.
