"Ta osoba náš stroj neslyší."

Translation: That person does not hear our machine.

[ion1122]

Our machine does not hear that person:
Tu osobu náš stroj neslyší.

Right?

[J.C.M.H.]

Right!

[REeflZXI]

I believe that "osoba" might also translated as "individual."

[thaisdegouveia]

Why in this case I can not use the gerunds?
The person is not hearing our machine.

Would člověk not be the more usual word for person?

[VladaFu]

What should "useful" mean here?

most sirect equivalents are

osoba - person
člověk - human, man

but we have a lot of overlap.

[GinaHearn4]

I did say 'usual' not 'useful'. While I have come across osoby eg in lifts, showing the maximum number of people allowed, I see člověk more often in the singular. So if they are interchangeable, I will use osoba in future because I find člověk hard to say!
