Synonym discussion
Sense: noun/1
The quantity and process senses of consumption overlap with three common near-synonyms. Usage (e.g. 'water usage') focuses on how something is employed rather than how much is used up — you can measure usage without implying depletion. Intake is narrower: it applies only to what enters the body (food, air, liquid) and carries a biological or nutritional frame. Expenditure is the most formal of the group and typically refers to spending money, energy, or time rather than physical resources. For example: 'The city reduced its energy consumption by 15%' — a quantity that could also be called energy usage, but calling it energy expenditure would sound too financial. 'The doctor asked about my daily water intake' — intake works here because it is about the body, but consumption would feel clinical and impersonal.

Etymology
Consumption comes from Latin 'consumere', which combines 'con-' (altogether, completely) and 'sumere' (to take up, take possession of). It passed through Old French 'consumption' and entered English around the 14th century. The original meaning was 'wasting away' — which gave us the now-archaic disease sense (tuberculosis). By the 16th century, it had broadened to refer to any act of using up resources. The economic meaning emerged during the Industrial Revolution as thinkers began to distinguish between the creation of goods (production) and their use (consumption).
