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:


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:


> 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?
