The word 'consumption' refers to the act of using up resources or goods. It can also pertain to the process of eating, drinking, or otherwise utilizing something. In economics, it often describes the use of goods and services by households or individuals. In a medical context, it can refer to the condition of being affected by a disease, especially tuberculosis, which used to be known as "consumption" due to the way it consumes one's health.
The word 'consumption' comes from the Latin word "consumptio," which means "a using up," from "consumere," meaning "to take up, use up." The term entered Middle English through the Old French "consomption."
