How do you say how are today in welsh?

There are a few ways to say "how are you today" in Welsh, depending on the formality and context:

Formal:

* Sut mae chi heddiw? (This is the most formal and literal translation.)

* Sut mae pethau heddiw? (This is a more common way to ask "how are things today?")

Informal:

* Sut mae'r pethau? (This is a more casual way to ask "how are things?")

* Sut mae 'na? (This is a very informal and friendly way to ask "how are you?")

Note:

* In Welsh, you use "chi" for "you" when speaking formally and "ti" for "you" when speaking informally.

* You can also use "da iawn" (very good) or "ddim yn ddrwg" (not bad) as replies to these questions.

So, depending on the situation and your relationship with the person you're speaking to, you can choose the appropriate way to ask "how are you today" in Welsh.
