Is there a difference between "om" and "bărbat"?
Wiktionary says that "om" is a general word for human, but "people" was not accepted here. I'm going to report it, but the Romanian module doesn't seem to get much attention these days.
The sentence is about one person, not several people.
Can you say "a wise man?"
wise = înțelept
"A smart person understands" is not allowed
