PhthisicPhthisic or phthisis
[From Greek phthisikos through Latin and Old French]
- Pulmonary tuberculosis.
- Any of various lung or throat affections; a severe cough; asthma.
This term, once very common but now extremely rare, had a large number of euphonious derivatives, e.g. phthisiology, phthisiologist, phthisiophobia, phthisicky, phthisiotherapy, and phthisiotherapist. Not to be confused with phthiriasis which means an infestation with lice.
