"Do you hear that man?"
Translation:Słyszysz tamtego mężczyznę?
masculine nouns that describe people 9masculine personal)
nominative ci, tamci
accusative=genitive tych, tamtych
all other plural nouns (masculine nouns for things and animals, all feminine nouns, all neuter nouns= we call it not masculine personal nouns)
accusative=nominative te, tamte
genitive tych, tamtych
Depends on the case, and the gender. "słyszeć" needs Accusative. The Accusative masculine form of "tamten" is either "tamtego" or "tamten". We here prefer to teach that "tamtego" is for animate nouns, and "tamten" for inanimate.
The thing is, that a lot of things, mostly food and beverages, are considered grammatically animate for no real reason. But that's not a problem here. "mężczyzna" is definitely animate, so it's "tamtego mężczyznę".
the trick is to look at declension table of the noun. if accusative=nominative for a noun, it has to be the same for pronoun/adjective. If accusative=genitive for a noun, the same for a pronoun/adjective. Some masculine nouns have accusative different from either, you use accusative=genitive.
