nos da a chroeso
The word for "welcome" in Welsh is "croeso".
You just said it yourself. If you want to say it in another language, you need to say which one.
Croeso i fy ... (welcome to my...)Then it gets tricky.Naturaly you'd mutate (treiglo) delicatessen to "fy nelicatessen" however seeing as it's not a Welsh word perhaps it'd be better to say:"Croeso i'r delicatessen" = "welcome to the delicatessen"
You can reply "Croeso" which means "You're welcome" in Welsh.
You say "shukran" which means "thank you".
당신은 환영합니다 = You are welcome
