I must say I don't see the point of Irish signs in a country where the everyday language is English and only a minority of the population speak Irish fluently. But if that's what some people want, it doesn't really bother me one way or the other.
People justify dual language signs on the basis that they promote linguistic diversity, they encourage people to learn Irish and they recognise our close ties to the Republic of Ireland.
But there are only 72,000 Irish speakers in Northern Ireland out of a population of two million, so I wouldn't have thought dual language signs were a high priority.
And why only road signs? What about all the other signs on public buildings? Shouldn't they also be dual language?
There's a big lobby to have dual language signs on the new Grand Central Station, and an equally big lobby not to. I await the outcome with interest.
Personally I have no desire to learn Irish, especially as it's a famously hard language to learn. Jenny has been learning Irish for some time despite all its oddities and its fiendish pronunciation. But fluency is still a long way off.
