Good stuff Eddie.
Interesting the names of some of the Welsh mountains. Some of the meanings are virtually identical to ones in Scotland, showing the common ancestry of the two languages. This despite the fact they've been separated for thousands of years. The word Fawr (as in Glyder Fawr, pronounced VOWr) in Welsh is a mutated form of mawr, meaning large or big. The gaelic equivalent is mor (MORE), which means the same thing and is pronounced very similarly.
The same is true for the other Glyder (Glyder Fach, pronounched VAch). This is the 'small' Glyder (i.e. bach), very similar to gaelic beag, meaning the same thing.
Moel is also very similar to gaelic maol, both meaning a bald or bare hill.
Fascinating stuff!
