A steep valley or ravine, especially in hilly or mountainous terrain; also a narrow passage or gorge.
From Old English 'cloh' or Middle English 'clogh,' possibly related to Old Norse 'klauf' (claw or clutch), referring to how steep valleys seem to grip the landscape.
Many English place names contain 'clough'—like Cloughton or Cloughhead—and if you visit the Pennines or Peak District, you'll see these dramatic narrow valleys carved by streams over millions of years.
