Open valleys between hills or mountains, especially those with gentle slopes and typically grassy landscapes, common in Northern England.
From Old English 'dæl' and Old Norse 'dalr' both meaning valley; extremely common in British place names (like Yorkshire Dales), these cognates appear across Germanic languages.
The reason Yorkshire, Derbyshire, and England's north are covered in place names ending in '-dale' is because Viking settlers from Scandinavia left linguistic imprints—their word for valley literally shaped how we name the landscape today.
