From Latin morbus.


morbus (plural morbuses or morbi)

  1. (medicine, formal) A disease.
    • 1838, Thomas Hood, “A Rise at the Father of Angling”, in The Comic Annual, page 47:
      I thought he were took with the Morbus one day, I did with his nasty angle!
      For “oh dear,” says he, and burst out in a cry, “oh my gut is all got of a tangle!”
    • 1846, William Andrus Alcott, The Young House-keeper: Or, Thoughts on Food and Cookery, page 214:
      Probably no small share of our cholera morbuses, diarrhœas, and dysenteries, have their origin in this source.
    • 1979, F. Kraupl Taylor, D. M. K. Taylor, The Concepts of Illness, Disease and Morbus, page 117:
      Unfortunately, most of the morbi accepted in modern medicine are only taxonomic entities whose causal derivation is merely partially known and therefore polygenic.
