"I want to eat something good."

Translation: Chcę zjeść coś dobrego.

[BogdanResh]

Coś, but why not czegoś?

[Randwulf]

Could it be also "coś smacznego"?

[Stefan873422]

Why dobrego and not dobry?

[Jellei]

"coś" requires a form that ends with -ego. Whether it's Accusative or Genitive, I'm still not sure. Probably Genitive, as 'coś' itself is neuter and for neuter, only Genitive ends with -ego.

[Nico515253]

Feels like French and Italian (quelque chose de bon/qualcosa di buono) and therefore not as odd as many Polish constructions.
However, I am struggling with the perfective business. I understand the principle of a single, finished action, but what would be the difference between 'co chcesz zjesc/ and co chcesz jesc'? Or is the second not possible anyway? Maybe it would have to be 'co lubisz jesc'? Thanks!

[Jellei]

"Co chcesz jeść?" is possible, it's not even that weird to my ear, but "zjeść" makes more sense.

"Co lubisz jeść?" surely makes more sense than with 'zjeść' because this is a general notion.

[AnCatDubh]

Is coś always masc.?

[immery]

it's always neuter. but for some reason nominative and accusative of something+ adjective, are

coś+ adjective in genitive

[JoanieKatz]

Can't "zjesc" be at the END of the sentence as well?

[Jellei]

That would sound rather strange.

[JoanieKatz]

misspelling "zjescz" is a TYPO, isn't it? not a Wrong word

[Jellei]

True. The algorithm isn't good with understanding the types of mistakes.

[J_Rzesiewicz]

If a Z is at the beginning of an infinite does it mean it is just happening once?

[Jupy015]

something like that, it's a perfect verb

[JerryMcCarthy99]

However, not all perfective verbs are indicated by a "z". There are many possibilities....
