An isthmus is a narrow strip of land with water on both sides that connects two bigger land masses, see e.g. the L'Isthme de Penthièvre, which connects the peninsula of Quiberon with mainland France: https://www.openstreetmap.org/node/2450239624#map=11/47.5485/-3.0755 Promontories, headlands and capes seem to be almost synonymes, see e.g. the definitions by Merriam-Webster: * promontory: (a) a high point of land or rock projecting into a body of water; (b) a prominent mass of land overlooking or projecting into a lowland * headland: a point of usually high land jutting out into a body of water: promontory * cape: a point or extension of land jutting out into water as a peninsula or as a projecting point The difference from a peninsula (from Latin paeninsula = 'almost island') seem to be the connection to the mainland: it is significantly wider in case of a promontory/headland/cape, but an isthmus in case of a peninsula. Merriam-Webster: * peninsula: a portion of land nearly surrounded by water and connected with a larger body by an isthmus See also the diagrams on this web page: http://www.eschooltoday.com/landforms/what-is-a-cape-and-peninsula-landform.html > I would think all of these should come under natural=xxxxx, & should be > mapped as they are named: =headland, =cape, =peninsula, =promontory etc etc If promontory, headland and cape is already part of the name, why duplicating it with different tags?
