"The soup is tasty."

Translation: Zupa jest smaczna.

[Smithers1277]

How do I know when to use zupe, zupa/smaczna, smaczne?

[shairGorgi]

You're not exactly teaching grammar here, so we never know when it ends in a, e, or y. Please advise.

[Angi845317]

What is the difference between smaczna and smaczne?

[ManuelHent1]

Smaczna is feminine, smaczne is neuter, I believe.

[victor.pacanza]

Why does it have to be fem? If I say Zupa jest smaczne is that wrong?

[Jellei]

It's wrong. The noun "zupa" is feminine (like 99% of nouns that end in -a in Nominative), so the adjective has to match.

[AussieEeyore]

Why is "zupę jest smaczne" wrong?

[Jellei]

"zupę" is the Accusative form, used for the direct object of the sentence (Jem zupę = I am eating soup). As "the soup" is the subject of the sentence here, it needs to be in Nominative, which is "zupa".

"zupa" is a feminine noun, so the adjective "tasty" also needs to be feminine, which is "smaczna".

[BethLofy]

I spelled smaczna like this smaczne, why would the whole sentence be counted wrong? This is confusing when to use which spelling!

[Jellei]

You used a wrong grammatical form, so this is definitely a mistake.

The adjective needs to match the noun it describes. "zupa" is a feminine noun, so the right form of the adjective is "smaczna".

Your "smaczne" is either neuter singular or 'not masculine-personal plural' (non-virile).

[BethLofy]

Is very hard to remember the polish forms! Thank you for your response.

[Vero15_87]

Why not: "zupa to smaczny"?

[immery]

to is only for "noun is noun" sentences.

"noun is adjective" needs "jest" without "to", and adjective in nominative

[Frecklebuster]

You have solved my bewilderment about 'byc' by saying that you need the adjective in nominative case. I've been trying to put the adjective in Instrumental case each time. Now I've got it!! Thank you.

[Martin207584]

I'm getting "correct, but watch out for typos" on using "...smaczny". Isn't that even grammatically wrong? If so, it should not count as a correct answer.

[Jellei]

The grading algorithm has been too lenient already. I agree that this should be failed as it's a different grammatical gender.

[TimoBald]

Why is zupa to smaczne false?

[Jellei]

1. You can only use the construction with 'to' if you have nouns (noun phrases) on both sides. Here you just have a standalone adjective after, so you need "jest".

2. The grammatical gender of the adjective has to match the noun it describes. "zupa" is a feminine noun, so it needs the feminine form "smaczna".
