asthma 哮喘

来自希腊语，拟声词。

asthma: asthma: [14] The original idea contained in asthma is that of ‘breathing hard’. The Greek noun asthma was derived from the verb ázein ‘breathe hard’ (related to áein ‘blow’, from which English gets air). In its earliest form in English it was asma, reflecting its immediate source in medieval Latin, and though the Greek spelling was restored in the 16th century, the word’s pronunciation has for the most part stuck with asma.
=> air
asthma (n.): late 14c. asma, asma, from Latin asthma, from Greek asthma "short breath, a panting," from azein "breathe hard," probably related to anemos "wind." The -th- was restored in English 16c.
