means A condition caused by not getting enough of the right nutrients, whether from too little food, too much of the wrong food, or a body that can't absorb what it needs.

from Built from Latin: 'male' meaning badly, and 'nutrire' meaning to nourish or suckle — the same root that gives English 'nurse' and 'nutrition.' So the word is literally 'badly nourished,' a plain, clinical label stitched together in the 1800s when doctors needed precise terms for the gap between eating and actually being fed.
