metabolism

Etymology

It is from Ancient Greek μεταβολή (metabolḗ, “change”) with the English suffix -ism, formed after the adjective metabolic;^[2][3][4] Etymonline takes it from French métabolisme,^[5] and Barnhart sees both the English formation and the French word behind it.^[6] The Greek noun comes from μεταβάλλω (metabállō, “to change”), made of μετά (metá) and βάλλω (bállō, “to throw”),^[5][7][8] from Proto-Indo-European *gʷelə- (“to throw, reach”).^[5][7] Merriam-Webster treats it as an international scientific word.^[9]

Earliest recorded meaning

Structural change in a tissue: 1872, in W. A. Hollis in the Journal of Anatomy and Physiology, a rare sense soon obsolete.^[2] The lasting sense, the chemical processes by which a living body maintains itself, follows in 1878, in Michael Foster's Text Book of Physiology;^[2][5][6][9] Dictionary.com dates the word 1875–80.^[10]

Semantic evolution

The adjective metabolic is older: Barnhart finds it in 1743, in Henry Fielding, meaning "involving change", and the physiological sense in 1845, in a translation of a French book on physiology.^[6] A theological sense, the change undergone by the bread and wine of the Eucharist when they are consecrated, appears in 1876, after German Metabolismus (1856); the Greek word had been used of the Eucharistic elements in Hellenistic times.^[2] Etymonline notes that the word has also been used in poetics and entomology.^[5] Figurative uses, of a society or a mind, are recorded from 1900.^[2] Since 1960 the word, capitalised, has also been the name of a modernist movement in Japanese architecture that treated the city as a living organism.^[2]
