So my uncle/God Father recently passed, and was a very important part of my life. Our family is also Scottish (clan name munro) and my uncle was very proud of his heritage.

I wanted to get the saying "His like will never exist again" in Scottish Gaelic.
I've searched the internet and the most common spelling of this phrase is
"Cha bhithidh a leithid ami riamh". If you search that phrase in google you'll see many people use that spelling. But it never hurts to be accurate

Now on another scottish forum, someone gave this spelling of the phrase
"Cha bhithidh a leithid ann a-riamh" pretty similar.

So i'd just like some opinions on what would be most accurate (i know some words may be old gaelic and some new).

Much appreciated!
