marl
UK[mɑːl]US[mɑːrl]
n
A crumbly soil consisting of clay and calcium carbonate, used especially as a fertilizer.
Etymology
The word 'marl' has a journey rooted in the practical language of agriculture and geology. It entered English from Old French, having descended from the Late Latin term 'margila', a diminutive form of the Latin 'marga', which referred to a type of crumbly, fertile earth. The ultimate source is likely a pre-Latin, possibly Gaulish substrate word, reflecting the material's importance in ancient European farming. Over centuries, the term's meaning has remained remarkably stable, preserving its core reference to a specific calcareous clay soil valued for improving land.
Analysis
The word 'marl' is a simplex loanword. It entered English from Old French 'marle', which derived from Late Latin 'margila', a diminutive of Latin 'marga' (meaning 'marl' or 'clayey earth'). The ultimate origin is uncertain but may be Gaulish (Celtic).
Examples
The farmer spread marl on the fields to neutralize the acidity of the soil.
The distinctive white cliffs in that region are composed primarily of marl.
Historical records show that marl has been used as a fertilizer since Roman times.
