"De kaas is een beetje oud."

Translation: The cheese is a bit old.

[Emkoshka]

But that's just how Dutchies like it! ;)

[EricVanErt]

Oude kaas is goede kaas. :)

[ClassiDuo]

I tried "tad" instead of "bit"--duo didn't like that (maybe a tad too slangy?)

[miajav]

The cheese is slightly old? Not accepted

[Susande]

It should be, you can report it.

[Frigooss]

The audio of the Dutch sentence is bad. I hear 'De kas' and not 'de kaas'

[nossey]

can't "wat" also mean a bit? What's the difference?

[kookooroodza]

True.
There is no difference in meaning. 'een beetje' is clearer because it means only the one thing, while 'wat' can also mean 'something' and 'what' and indeed 'somewhat'.

[HazelEllis2]

as an English speaker- the 'proper' English should be "the cheese is a little old". Duo marks this as wrong.
"a bit old is" a bit slang!

[GborPaksi1]

The best

[MattBenet]

Actually, I don't think it should. They may be interchangeable in this case, but not in all cases. We need to know the difference

[CareyFleetwood]

Any reason "The cheese is quite old" is not accepted?
