What does consumptive mean?
Consumptive has two related strands of meaning. Its best-known historical sense describes someone suffering from consumption — the old name for pulmonary tuberculosis — a disease that, in the era before antibiotics, caused dramatic weight loss, pallor, and a persistent cough. Because tuberculosis loomed so large in nineteenth-century life and literature, the consumptive character became a stock figure in fiction, from opera heroines to Dickensian invalids, giving the word strong literary and period associations today. Since medicine abandoned 'consumption' in favour of 'tuberculosis', this sense now reads as historical rather than clinical. A second, broader sense describes anything tending to consume or deplete — consumptive habits, consumptive demand on natural resources. The word derives from Latin consumere, 'to use up entirely', sharing its root with consume and consumption. It remains useful for writers seeking a precise, evocative term, whether evoking gaslit sickrooms or unsustainable appetites.

Etymology of consumptive
Consumptive comes from Latin consumere, meaning 'to use up, waste, or spend completely', formed from com- ('together, thoroughly') plus sumere ('to take'). It entered English via the noun consumption in the sixteenth and seventeenth centuries, when 'consumption' named the body-wasting disease we now call tuberculosis. English shares this root with words such as presume and presumptive (from the same Latin verb sumere) and with sumptuary, relating to expenditure.
