Chi or Chy, is Cornish for House,
tŷ is the Welsh equivalent... not too distant I think...
When we were choosing a name for the house down here at the Edge of the World, we considered Chi/y Agan as it is a frequent naming convention down here... What really swung it for us was that Tre is Home... whereas Chi/y is house... and we felt that our home was better than our house...
I was lucky enough to find a web site on line, that offers online information on cornish names/pronunciations and meanings... improved my knowledge of the language and culture immensely.
A bonus today, meanings of cornish town names...
Camborne = Curve of the hill
Camelford - Curved river + ford
Carbis Bay - Cart bridge + bay
Cardinham - Hill fort
Carnkie - Dog carn
Carrick Roads - Rock anchorage
Chacewater - Stream in the hunting grounds
Charlestown - Named after Charles Rashleigh
Cubert - St Kubert
Cury - Priest's name (Corentyn)
It makes me want to visit them.. well apart from Camborne which I go to fairly frequently.
