IPA: /ˌʌndərˈnjuːtrɪʃən/
KK: /ʌndərˈnjuːtrɪʃən/
A condition where a person's body does not get enough nutrients because they do not eat enough food or their body cannot absorb nutrients properly.
Many children in developing countries suffer from undernutrition due to food scarcity.
Undernutrition is formed from "under-" (meaning below or insufficient) and "nutrition" (from Latin "nutritio", meaning nourishment or feeding). The word describes a state of having insufficient nourishment or nutrients.
Think of 'under' meaning below or insufficient, and 'nutrition' referring to nourishment — this helps you remember that undernutrition means not getting enough nourishment.
