How do you say god bless in welsh?

There isn't a direct, single-word translation for "God bless" in Welsh.

Here are a few options, depending on the context:

Formal:

* "Duw bendithio" - This is the most literal translation, meaning "God bless."

* "Bendith Dduw arnoch" - This translates to "God's blessing on you."

Informal:

* "Bendith" - This simply means "blessing" and can be used as a general well-wishing.

* "Cymro'n dda i ti" - This translates to "Good Welshman to you," and is a more colloquial way of saying "God bless you."

The best option will depend on the specific situation and your relationship with the person you're talking to.
