Thank you! Here’s a rough guide to pronouncing these place names:

Ynys Lochtyn = “UNus LOKH-tun” Llangrannog = “shan-GRAN-og”

The double-l “ll” letter in Welsh is pronounced like a “sh” sound, but harsher and further back in the mouth.

Similarly, the “ch” letter is similar to the Scottish Gaelic “ch” sound they use for words like “loch”.
