喘
chuǎn · HSK 7
to pant
😮💨 mouth + ear + nose = chuǎn, all the airways gasping at once
The character 喘 combines 口 (mouth) with 耑 (related to端, meaning end/extremity). Sound-wise, chuǎn echoes 'churn' — your lungs churning air when you pant after a sprint.
喘 — mouth 口 + 而 (phonetic)
A semantic-phonetic compound: 口 (mouth) gives the meaning, since panting and gasping happen through the mouth, while 而 supplies the sound. Originally meaning to breathe heavily or pant, it later extended to asthma and labored breathing in medical contexts.
