How do you say buddy in Welsh?

There isn't a direct translation for "buddy" in Welsh that captures the same casual and friendly tone. However, here are some options depending on the context:

Informal:

* Cymro: This literally means "Welshman" but can be used affectionately for a close friend, similar to "mate" in English.

* Ffrind: This means "friend" and is a good option for a casual friend.

* Cyd-Gymrawd: This means "comrade" and is slightly more formal, but can still be used with friends.

More formal:

* Ffrindiwr: This is a slightly more formal term for "friend."

It's best to choose the word based on your relationship with the person and the situation. For example, "Cymro" would be more appropriate for a close friend, while "Ffrind" might be better for someone you're not as close to.

Remember that using slang terms like "buddy" in another language can sometimes sound strange or unnatural. It's best to stick to more formal options unless you're confident in your understanding of Welsh slang.
