"Talwch chi"

Translation: You will pay

[smidgit]

Just wondering - can this be used in the same idiomatic way in English when you say "You will pay!" when you're angry and want to take revenge?

[EllisVaughan]

I certainly can't see why not, I probably would though that might be just me using anglicisms in my Welsh.

[Rhaidyn]

Would you use the formal version in this case or the informal, in your opinion? It would seem odd to me to have to use a polite way of saying this when I'm supposed to be demanding revenge from someone who's done me wrong.

[DavidHough15]

It could be that you're talking to more than one person.

Conversely, I think it would seem strange to me to use the familiar version in that instance. I get the impression that ti vs. chi in singular is more a choice of familiarity than politeness (though, being overly familiar with someone can be considered impolite).

[Julianbark6]

I think using the familiar could add to the threat or insult; perhaps a bit like calling someone "mate" or "pal" when they're not.

Sounds ominous!
