asthma
UK: ˈæsmə | US: ˈæzmə
n. a chronic respiratory condition marked by difficulty in breathing, wheezing, and coughing due to inflammation or obstruction of the airways.
The word "asthma" originates from the Greek ásthma (ἆσθμα), meaning "panting" or "short-drawn breath." The Greek root sthma derives from aíein (to breathe heavily), reflecting the labored breathing characteristic of the condition. The prefix a- intensifies the sense of struggle. Over time, the spelling evolved through Latin (asthma) into Middle English, retaining its core meaning of respiratory distress.
