Not as many as it seems. I'm a native English speaker, and I'm best with Spanish and Russian.
'dz' is pronounced like dź. Is this only when followed by an -i? The 'ci' sounds about the same. Is it voiceless or voiced? Thanks for your contribution to this course!
ć, ś, ń, ź, dź sounds all are spelled like this:
-ć,ś,ń, ź, dź before consonant and at the and of word - ci, si, ni, zi, dzi before a vowel.
- i before vovel is short, almost silent, it just "softens" consonant before,
nie sounds like "ńe", but nic souds like "ńic"
ń, ź, dź are voiced, ś and ć are voiceless
is dzieci is this sentence nominative or accusative (I know it's the same word, but from a sentence structure point of view, which is it?)
