"Ten ser jest zupełnie zielony!"

Translation: This cheese is completely green!

[AnjaNoppinger]

We should all visit Poland to see green cheese!

[Emwue]

Actually, that's not our thing – green cheeses:

• Cherni Vit – of Bulgarian origin
• Sage Derby – English
• Schabziger – the Canton of Glarus in Switzerland

;)

[Jack.Elliot]

and they are lovely

[AnCatDubh]

That’s a thing actually.

[br0d4]

Or this one, perhaps.

[immery]

did you mean white cheese - ser biały https://pl.wikipedia.org/wiki/Twaróg

Why is "This cheese is all green" not accepted (while "Your coat is all wet" is accepted for "Twój płaszcz jest zupełnie mokry")?

[Jellei]

Makes sense, added.

[dlhgl]

Thanks, not only for adding this, but also for all your helpful comments for us Polish learners - I already learnt a lot from it :-)

[Jellei]

Always happy to help :)

[Valkorus]

Happy Saint Patrick's day!

Why "this cheese is quite green" is not accepted?

[warfreak2]

Because "quite green" is about how green the cheese is, whereas "completely green" is about how much of the cheese is green.

[JaneOsis]

Confused by why 'zupelnie' is not at the beginning of the sentence when, in previous sentences, this was the case and, as I understood it, thus emphasises the completeness?

[br0d4]

The word "zupełnie" refers always (probably) to the next word, it makes emphasis - so it may appear on various positions in the phrase.

[NieNieNieNie]

Can it mean the cheese is bio/eco/natural (dunno the English word for that)?

[br0d4]

No. The word "zielony" can be used in that meaning as addition to nouns that by no means could possibly be actually green - generally abstract nouns. "Zielona energia" and "zielone technologie" are the only two that I can bring to my mind at this moment.
