1. The Irish language
Ahhhh, Gaeilge. It may not be evolving, but it’s still there, on ATMs, at bus stops, and in some parts, it’s still thriving. Seeing as every Irish person has to take it for their Leaving Cert, it enables even the least fluent of us to have a solid linguistic back-up when travelling. We can bitch and moan about people in our immediate vicinity without them having a clue what we’re saying. Granted, slurs don’t get much more vulgar than “Póg mo thóin” (Kiss my ass), but regardless, it’s something we’ve got that no one else does. So there.
