Lowena dhis!
There are several ways of saying "Cornwall welcomes Sawhney":
"Yma Kernow ow tynerghy Sawhney!" (meaning "here and now" implied)
"Kernow a dhynnergh Sawhney!" (meaning "will do now and in future")
You can also use the verb "welcomma" instead of "dynerghy":
"Yma Kernow ow welcomma Sawhney!"
"Kernow a welcom Sawhney!"
Especially in the West, Cornish speakers like to insert a b before the m in "welcomma" and pronounce "welcobma", so you get:
"Yma Kernow ow welcobma Sawhney!"
You may know how to pronounce "Mousehole" correctly in English, but in Cornish it's "Porth Enys"! ;-)
