Irregular, sharp-edged fragments or blocks of limestone created by weathering and erosion, often forming a jagged terrain.
From Middle English 'clint', possibly from Old Norse 'klint' (rocky crag or outcrop). The term has been used in geology and regional British English for centuries.
Limestone landscapes with clints and grikes (cracks between them) are called 'karst,' and they're perfect case studies for how water chemically dissolves rocks over millennia—the clints are basically what's left behind.
