coal-mining

The compound noun "coal-mining" is a transparent combination of two English words, each with deep historical roots. "Coal" descends from the Old English col, a term for burning charcoal or ember, which has cognates across Germanic languages. "Mining" derives from the Old French mine, likely of Celtic origin, referring to an ore deposit or tunnel, combined with the Germanic-derived suffix -ing that denotes an action or its result. The literal logic of the compound is perfectly clear: it names the specific industrial action (mining) directed at a specific mineral resource (coal). This straightforward compounding reflects a common pattern in English for creating precise technical and occupational terminology.
