No surprise either, since all the lawyers in this course seem to be off apple-hunting and getting portraits painted of themselves :D
In my opinion this is correct as it is on duolingo. This is so hard to determine.
In a situation like this: - Hey man, what are you doing? - I am waiting for a lawyer. The act, the waiting is much more important for us, than the person. But, if i say "ügyvédet" i know who teh exact person is, i just dont want to bother you, and i expect the next question to be, "For how long"?
2nd situation: -What do you do in the afternoon? - I wait for a lawyer. This case, the lawyer got the importance. In that case, i don't know personally who am I waiting for (maybe i got a recommendation from someone else), and I expect the next question to be: "Really? who? or why?.
I hope i could help.
So here on Duolingo, I cannot know if the activity of waiting or the person I am waiting for is of higher importance, right? Do I need a context to determine if I use "Egy ügyvédet várok" or "Egy ügyvédre várok"? Does Hungarian differentiates between present simple and present continuous tense? How?
No, it does not differentiate. Respectively just using the context... Here is the similar question explained: https://www.duolingo.com/comment/16589714$comment_id=16700906
Btw, here I wrote the same answer "I am waiting for a lawyer." - and it was marked as wrong.
