About isthmus names

An isthmus is a narrow strip of land that joins two larger lands and keeps two bodies of water apart. On real maps the plain form is 'Isthmus of' plus a nearby city or region, as with Panama, Suez and Corinth, but the people who live on one usually name it for what it does. It is the neck or waist of the land, the bridge you can walk, the short haul that saves a long voyage, or the line an army has to hold.

This list of 1,000 names follows those jobs. There are 'Isthmus of' forms with invented regions, neck, waist and narrow names, landbridges and tidal causeways, and portage names for places where boats are dragged overland, an old practice remembered in the Diolkos trackway at Corinth, in Scottish Tarbert names and in the Norwegian word eid. Two-seas names pair the waters on each side. Others mark walls, gates and toll lines, canal cuts, or strands of marsh, dune and shingle.

You will also find forms in Spanish, Portuguese, Italian, French, German, Dutch, Norwegian and Latin, and a small share of real isthmuses, each marked (real) so you can tell them from the invented names. The rest are invented for maps, games and fiction, though plain descriptive forms can match real small places.

How to choose isthmus names

  • Decide what the isthmus does in your world before you name it. A trade shortcut suits a portage or carry name, a contested frontier suits a wall, gate or toll name, and a quiet backwater suits a marsh or dune name.
  • Use the two waters. Names such as Northmere Southmere Link or Twain Seas Strip work best when you swap in the seas, bays or lakes from your own map.
  • Give it two names, the way real places have them: a formal map name (Isthmus of Venmarch) and what the locals say (The Long Carry).
  • Match a foreign form to the people who hold the land. An Istmo, a Landenge and an eid on the same coastline tell the reader who settled where.
  • Be careful with a bare Neck. Many readers take 'Gull Neck' for a peninsula, so add what it joins or what lies on each side, as in The Neck of Two Bays.

Frequently asked questions

What is an isthmus?

An isthmus is a narrow strip of land with water on both sides that connects two larger areas of land. The Isthmus of Panama, for example, joins North and South America and separates the Caribbean Sea from the Pacific Ocean. It is the mirror image of a strait, which is a narrow stretch of water between two lands.

What is the difference between an isthmus and a peninsula?

A peninsula is land that sticks out into the water and is surrounded on three sides. An isthmus is the narrow piece that ties such a land to the mainland, or ties two mainlands to each other. The Isthmus of Corinth, for instance, joins the Peloponnese to the rest of Greece.

Are these the names of real places?

Most are invented. A small share of well-known isthmuses are real and carry a label in the name itself, such as Isthmus of Panama (real), Kra Isthmus (real) and Karelian Isthmus (real). Plain descriptive names, above all the Norwegian -eidet forms, can also match real small places. The list is a source of ideas for stories and games, not a gazetteer, so look a place up before you rely on it for geography.

What do portage names like Tarbert and eid mean?

Tarbert comes from the Scottish Gaelic tairbeart, a place where boats were carried or dragged across a neck of land, and eid is the Norwegian word for an isthmus. Names in the list such as Wester Tarbert, Båteidet, The Keel Road and Greywether Portage all point to the same idea: a crossing short enough to haul a boat over instead of sailing around.
