malthusian

The word is a modern eponym, formed directly from the surname of the influential economist Thomas Robert Malthus. The suffix '-ian,' with its lineage tracing back to Latin '-ianus' and ultimately Greek '-ianos,' is a productive suffix in English for forming adjectives and nouns denoting association or adherence. Thus, 'Malthusian' literally means "of or pertaining to Malthus." The term encapsulates his core thesis, presented in his 1798 "Essay on the Principle of Population," which argued that population tends to increase geometrically while food supply increases only arithmetically, inevitably leading to checks like famine, disease, or war. The word's evolution from a simple proper name to an abstract socio-economic adjective demonstrates how a theorist's name becomes shorthand for an entire doctrine or worldview.
