The phrase you want translated is quite unusual, with its expression in English being somewhat unusual, so simply ask someone who speaks Welsh fluently, or at least speaks Welsh better than me to give you an answer. I’m sure they will be along soon
Just to say that all the replies before mine were, in my view, marvellous!
Edit- @mikeellwood, I’m certainly no expert, but “ein cartref tragwyddol” summons up images of the grave (or, more happily, heaven) to me, so I think your suspicions may be correct! And my vote is with you on “ein cartref am byth”. But as you say, better ask an expert for this!
I always wanted a little cottage called, yn gymraeg, ‘the home of my heart’ I got a liitle cottage in English speaking Gower and it would have been totally pretentious and out of place to call it anything so fancy in any language. ‘Cae Mor’ or ‘Devon View’ were the sort of names one had to have!! Where we live now in Scotland, anything but a number would be out of place!!
So, I never got my wish, but @aran, would "Gartre’nghalon’ have been an acceptable contraction as a name???
Diolch. but wouldn’t that be ‘a home’? I want the home, so do I have to say, “Y Garte Fy’nhalon’i” or something like that? How much joining up to make a name can one do?? Not that I’m ever likely to be able to use it!!!
