What does underfed mean?
Underfed describes a person, animal, or population that has not received enough food to meet its nutritional needs. The adjective is commonly used for children and animals, but it can also characterize communities or groups living with chronic food insecurity. It is more specific than simply hungry: hunger may be temporary, whereas being underfed usually implies inadequate nourishment over time. The term can sound clinical or documentary when describing severe deprivation, though it is also used in less formal contexts to criticize neglect or insufficient provision. Underfed can also serve as the past tense and past participle of the verb underfeed, meaning to feed inadequately. Thus, “the animals were underfed” may describe a condition they experienced, while “the keeper underfed the animals” identifies inadequate feeding as the action. Because its meaning is transparent and morally pointed, underfed is especially effective in reporting on hunger, poverty, and the failure to provide adequate food.
Having received too little food to meet nutritional needs.
"The clinic reported that several children had been underfed."
Used literally for inadequate nourishment and also more broadly for populations experiencing chronic food deprivation.
To feed a person, animal, or group an inadequate amount of food; the past tense and past participle of underfeed.

This verbal use is less common than the adjectival use and often carries a strongly negative implication.
Underfed is unusually transparent: it points to the problem and, by implication, the failure to provide enough food.

Where does underfed come from?
Underfed was formed in English by combining the productive prefix under- with feed, following the pattern of English compound adjectives. The resulting form functions both as an adjective meaning “inadequately fed” and as the past tense and past participle of underfeed. Feed itself comes from Old English fēdan, “to feed or nourish,” so the compound's central idea is transparent: being fed below what is needed.
