noun
dell
DELL/del/
A small wooded valley.
The dell has a grassy bottom enclosed by tree-covered slopes.

Etymology
Old English dell meant a hollow or valley, matching the small landscape depression named today. Direct survival is uncertain: the word may have been lost and later reborrowed from a closely related Germanic form.
