do you actually need to say 'the' ? in previous question, it said another acceptable answer was 'english actresses are pretty' even though there was an 'az' in original sentence
I don't hear "Mielyenek az angol rendörök" but "Milyenek az angol-z-endörök". I don't know why I'am earing a "zz" after angol and not a "r".
The name of the English police officers is Bobbies, which is not accepted here! The US equivalent expression for police officers in slang is cops.
I assume rendor = policeman, but also as officer. Actually it is politer to call a policeman "officer". So Duolingo should accept both answers as correct.
The word rendőr is a policeman, rendőrnő means policewoman, rendőrség means the police organisation, respectively the police station. Before WWII they has been called csendőr (csendőrnő, the female version never existed, because at that time women were not accepted). Officer means tiszt, but it is not used in everyday's parlance since you barely find one on the street.
