There is a stray fada in Dunmanway and in Cork city but generally An tSráid Ard is what I have seen.
A few months back, we passed through Dunmore in Co. Galway and I had to stop to photograph their own High St.
At first, I thought it may be a trick of translation similar to Listowel but neither ainm.ie or dúchas.ie have a record of a family name “Muchtar”.
Resorting to dictionaries Foclóir.ie, Teaglann.ie and Pota Focal all drew blanks – and not a suggestion as to an alternative.
My best guess, and completely without substantiation, is that it may have set out as ‘Uachtar’ meaning ‘top’. However somewhere between the spoken word and the sign-maker, ‘Ua’ became ‘Mu’.
As for the tuiseal ginideach, they would not be the first or last to not get their head around it – so did it start verbally as An tSráid Uachtair and end up as Sráid Muchtar?
Maybe a return visit is required…
