the.com/commodity market

means A marketplace where raw materials and basic goods — like grain, metal, or crude oil — are bought and sold, usually as standardized contracts rather than physical sacks of stuff.

from "Commodity" traces back through French to Latin commoditas, meaning convenience, suitableness, or advantage — the sense being that a commodity is something useful or fit for purpose. Over time the word narrowed from 'a convenient thing' to 'an article of trade,' and by the time organized exchanges emerged for mass-produced raw goods, 'commodity market' had settled into its modern sense: a place where interchangeable, no-frills goods get priced and traded at scale.
