Look up combe in Wiktionary, the free dictionary.
A combe (/kuːm/; also spelled coombe or coomb and, in place names, comb) can refer either to a steep, narrow valley, or to a small valley or large hollow on the side of a hill;[1][2] in any case, it is often understood simply to mean a small valley through which a watercourse does not run.[3][4] The word "combe" derives from Old English cumb, of the same meaning, and is unrelated to the English word "comb".[5] It derives ultimately from the same Brythonic source as the Welsh cwm (Welsh for 'valley'; pronounced [kʊm]), which has the same meaning.[6] Today, the word is used mostly in reference to the combes of southern[7] and southwestern England.
