"Nevím, a proto se ptám."

Translation: I do not know, and so I am asking.

[esamota]

Should "that is why" also be accepted as a possible translation for 'proto'. I don't know and that's why I am asking. Makes sense to me :)

[endless_sleeper]

It has always been one of the accepted translations :)

Can't proto be therefore? That's how i always understood it...

[BoneheadBass]

"Therefore" is also accepted.

[DpAiHk]

Can "tak" replace " proto"?

[Hatch-Slack]

"Nevím, tak se ptám." - It sounds ok to my ears, although I cannot imagine a context for it.
The meaning might be close, but not the same.
Maybe a native speaker can explain this to us?

[VladaFu]

It is accepted, although I like "a tak" much more here.

[DaffyDuck978329]

I do not know, so I ask sounds more natural

[BoneheadBass]

That is also accepted.
