What does "Erin go braugh" mean?

‘tis Irish Gaelic for Ireland forever, or so I’ve heard.

@Brian1946: well that makes sense, at least. Maybe now I’ll come up with something else to wonder about when I get bored at work. :)

From wikipedia

Erin go Bragh (pron.: /ˌɛrɪn ɡə ˈbrɑː/), sometimes Erin go Braugh, is the anglicisation of an Irish phrase, Éirinn go Brách, and is used to express allegiance to Ireland. It is most often translated as “Ireland Forever.”[1]

So, yes, it is Irleland forever

Ireland forever! ‘Tis just a wee bit of an Irish loyalty and love thing. Keep off the faerie hills, lass, lest the fae play a trick on ye!

The words “Aryan”, “Eire”, and “Iran” are all supposed to derive from a Proto-Indoeuropean root of self-designation, and with a meaning, roughly, of “Noble”.
