"We know both men."
Translation:Znamy obu mężczyzn.
I am having trouble understanding the difference between oba and oboje. Why is this not obojga?
It depends on gender and if a noun describes a person, and also on case.
obaj is for male person nouns
obie is for female nouns
oba is for neuter and male nouns that do not describe people
oboje is for:
- neuter nouns that describe people (dziecko=child, niemowlę=baby) ,
- pairs of people or person + animal that have different gender/sex
- pairs of nouns that are "always plural"
obojga is a form of oboje but in genitive.
obu is a form of obaj in accusative, and a form of obaj/obie/oba in genitive.
Can you give a couple examples of pairs of people or person + animal that have different gender/sex? Thanks in advance!
you need accusaive after znam. Plural ccusative form of "mężczyzna" is "mężczyzn" (it is masculine personal) ( -a ending masculine nouns have complicated relation to the declension rules, but masculine personal ones they still follow plural genitive=plural accusative)
Thank you, immery. I'm still struggling with determining when to use which case.
It's easy to know when to use nominative : Mostly subject of the sentence , and "to" sentences.
