Emphysema

/ˌɛmfɪˈsiːmə/noun

A lung disease in which the air sacs are enlarged and damaged, trapping air and leaving the patient short of breath.

The Greek roots

ἐν

+
φυσᾶν
physân
to blow, inflate

Literally: a blowing in

The story of the word

ἐμφύσημα is an inflation, from the verb used for blowing up a bladder or fanning a fire. Seventeenth-century English medicine applied it to any pocket of air trapped where none belonged, under the skin after an injury for instance, and surgeons still speak that way. The lung sense narrowed later: alveoli stretched past their elastic limit, so the chest fills with air that cannot be pushed back out.
