How do you say and the same to in Welsh?

There isn't a single direct translation of "and the same to you" in Welsh. It depends on the context and what you're specifically referring to. Here are a few options:

1. For general well wishes:

* A chi hefyd: This is the most common and general translation, literally meaning "to you also".

* A'r un i chi: This translates to "the same to you" and is more formal than "A chi hefyd".

2. For specific wishes:

* If you're responding to a wish for good health, you might say: Iechyd da i chi hefyd (Good health to you also)

* If you're responding to a wish for happiness, you might say: Heddwch a llawenydd i chi hefyd (Peace and happiness to you also)

3. For a more informal, casual response:

* Ti hefyd: This literally means "you too" and is a more informal way to say "and the same to you".

Ultimately, the best way to respond will depend on the situation and your relationship with the person you're speaking to.
