'There's no K or V in the Irish alphabet'
Someone needs to get the phone books out and inform all the people in Ireland with the surname Kavanagh that they are letting the country down badly.
I'll start with Cavan and Monaghan.
But it's a fact, there IS no K or V in the Irish language. There's also no J, Q, W, X, Y or Z.
Yes, some surnames and placenames have long since been anglicised and are accepted now. However, it's not likely this was done for the happiest of reasons in the first place, and I personally don't agree with anglicising first names (where we get to choose the spelling, unlike surnames where we inherit it) to something that doesn't work in Irish.
Orla for Orlaith, sure, it still works as Gaeilge and makes life easier in English. But Keeva doesn't work in Irish at all.
