"Bob wythnos"

Translation: Every week

[SantiMauricio]

Robert Wythnos.

But on a serious note, why isn’t this pob wythnos? I found this on the beeb about when to use soft mutations. Is this why?
-When adverbial expressions of time are used in sentences.

[shwmae]

That's exactly why!

non-adverbial: Mae pob wythnos yn wahanol "Every week is different"

adverbial: Mae'n wahanol bob wythnos "It's different every week"

[AngharadJones0]

Isn't each week the same thing.

[ibisc]

Yes.

[Nige101265]

couldn't it also mean "all week"? it was marked incorrect.

[shwmae]

That'd be trwy'r wythnos.

[ethnocontinuo]

Would "weekly" be an acceptable translation here?

[ibisc]

Unlikely. As a simple phrase to learn, 'every week' is the straightforward translation.

• Mae'r daith wythnosol 'na'n ofnadwy o ddiflas - That weekly journey is terribly boring.
