Can you have "dobre ludzie" ???
What is the difference between dobry and dobrzy?
Can I say 'dobry ludzie' as well?
no, "dobry" is correct only for 3rd masculine singular form
what is 3rd masculine singular form?
of this phrase, meaning "the good human"?
Why can't it be "dobrze" ludzie? Or does the word dobrze even exist? xD
It does, but it's an adverb, not an adjective.
