"Díky, ahoj!"

[ugrasergun]

Isn't ahoj both hi and bye. When i wrote, "thanks, hi" it did not accept

[zzxj]

Because context sorts out the correct meaning of ahoj. You wouldn't ever say "thanks, hi".

[MikeRejsa]

It says this means "Cheers, hello!"

Really? "Cheers"???

[VladaFu]

Sure, why not?

[cestina1]

I used "ta" instead of thanks just to test it out. Is "diky" not slang? Because if it is, then "ta", ugly though it is, should be acceptable....

[VladaFu]

No, it is not slang.

[VojtchKraj]

It's a shortened version of "děkuji". It is a bit less formal, but not slang.
