adj. characterised by a rough, uneven surface and a lack of smoothness, typically resulting from a sudden impact or fracture. Often used to describe the appearance of igneous rocks like granite.
The brash surface of the granite made it difficult to polish.
The geologist noted the brash texture of the rock, which suggested it had fractured under high pressure rather than eroding slowly.
The brash nature of the exposed bedrock provided a stark contrast to the surrounding sedimentary layers, indicating a history of violent tectonic activity in the region.
Uncertain. Perhaps from Scots brash, brasch (“a violent onset; an attack or assault”). Perhaps also related to Dutch bars (“stern; strict”), German barsch (“harsh; unfriendly”), Danish barsk (“harsh; rough; tough”), Swedish barsk (“harsh; impetuous”).
Compare American English bresk, brusk (“fragile, brittle”).
