An archaic or dialectal term for a narrow valley or hollow between hills.
From Old English combining elements 'an' or 'ean' (narrow) and 'field' (open land). This compound describes the geographical feature of a contracted valley space.
This word barely survives in place names in England, but it shows how medieval people described landscapes poetically—they didn't just say 'valley,' they used words that captured the narrowness and the feeling of being between things!
