About Celtic lake names

Three words do most of the work on a Celtic map. Loch is Scottish Gaelic, lough is the anglicized Irish spelling of the same word (in Irish itself it is also loch), and llyn is Welsh. This list of 1,000 names keeps the languages apart. A name followed by a place in brackets is a real water: Loch Maree (Wester Ross), Lough Corrib (Galway), Llyn Idwal (Glyderau). Sea lochs and tidal loughs are inlets of the sea, not lakes, and are marked as such.

The rest are built from real words. Gaelic names take an article and a genitive, so Loch an Fhèidh is the loch of the deer and Loch nan Eala the loch of the swans; a lochan is a small loch. Welsh uses y or yr, and a feminine noun softens after it, which is why cigfran (raven) gives Llyn y Gigfran. A language in brackets (Gaeilge for Irish, Manx, Breton, Cornish style) marks a built name in that language, and some native forms sit beside their map spellings, such as Loch Laomainn for Loch Lomond.

Plain descriptive names repeat across the hills. There is more than one Lochan Dubh and more than one Llyn Du, so a built name, with or without a language in brackets, may still match a real water somewhere.

How to choose Celtic lake names

  • Keep one language per region of your map: lochs in one country, loughs in another, llyns in a third. Mixed spellings on one shoreline read as a mistake.
  • Use a lochan for a small hill water and keep Loch for the big one below it. Lochan Uaine and Lochan na Lairige show the pattern.
  • Borrow the grammar, not just the words. If you swap the noun in Loch a' Chait or Llyn y Garreg, look up the article and the mutation in a dictionary first.
  • For a sea inlet, pick from the names marked sea loch or tidal. They suit harbors, narrow arms of the sea and ferry crossings better than an inland lake name does.
  • Search a name before you print it as fiction: a plain one such as Loch Buidhe or Llyn Mawr may belong to a real place.

Frequently asked questions

What is the difference between a loch, a lough and a llyn?

Loch is the Scottish Gaelic word for a lake or a sea inlet, lough is the English spelling used in Ireland for the Irish word loch, and llyn is the Welsh word for a lake. In this list Loch Shiel (Moidart), Lough Gill (Sligo) and Llyn Cau (Cadair Idris) show the three side by side.

Are the lakes in this generator real?

More than half are. A name with a region in brackets, such as Loch Rannoch (Perthshire) or Lough Mask (Mayo), is a real water, and so are the native forms shown with their map spelling. Names without brackets, and names with a language in brackets, are built from Gaelic, Irish, Welsh, Manx and Breton words or from real place names, although simple ones like Lochan Dubh or Loch an Oileáin (Gaeilge) exist on real maps too. Real waters in Brittany, Cornwall and the Isle of Man are listed under their French and English map names.

What does a name like Loch an Fhèidh or Llyn y Gigfran mean?

Loch an Fhèidh is Scottish Gaelic for the loch of the deer, and Llyn y Gigfran is Welsh for the lake of the raven. Both follow the usual pattern of the word for lake, an article and a noun in the right form, which is the pattern most built names here use.

Why are sea lochs marked separately?

A sea loch is a saltwater inlet, closer to a fjord than a lake, though Gaelic uses the same word for both. Names such as Loch Fyne (sea loch, Argyll) and Lough Swilly (tidal, Donegal) carry a mark so you can keep them for coasts and choose a freshwater name for an inland lake.
