"an amazing neighbor"
Yes even larger, bolder type than that would be extremely helpful. Very hard to read otherwise. I don't wear glasses, and I have to squint. The big blocks with thewords/ letters are great, but the sentences can be challenging to make out, and, after awhile, I have to quit because they make my eyes sore.
OK, now I caught on. When using the word bank, at least, if I had been paying attention I would have noticed. They offer ممتازة but not ممتاز, but they DO offer both جارة and جار. So, since only the feminine adjective is there, I was supposed to use the feminine noun.
All this is well for lazy me (doing this over as practice), and using the word bank. But when I was actually typing the responses, I assumed (for no legitimate reason, other than being a man I am more familiar with my male neighbors than with their wives) a male neighbor.
When you have the English words, and you're supposed to choose one of the three available Arabic options; give us the Arabic pronunciations as we tap the Arabic script. I don't know what it says becausei am not familiar with the Arabic written script, but since I've heard "neighbor" in Arabic, i think i could pick the correct answer if it said it aloud for me.
The audio is missing for مُمتارة! Also, Dulingo has made no effort pointing out that Arabic uses gender. In fact, on this comment page, the translation shows the masculine form of the sentence even though the female form was the requirement! Come on Dulingo! This can be done much better!
This exercise, (and many others!) does not have the correct response in the word bank. The required answer was جار مُمتايز (Not sure I spelled it correctly), but in the word bank it only had ممتيزة What is that final ة? It has appeared in several responses, and causes me to get "typo error".
(1) "This exercise (...) does not have the correct response in the word bank"
We can report the issue. Just click the "light bulb" symbol that is shown in the question section -- after we answered the question. Then, click "something else". If you are in Duolingo app, you can write your complaint. (But, I, myself, have never met this issue).
(2) "The required answer was "جار مُمتايز" (Not sure spelled it correctly)"
It is جار مُمتاز. You have a surplus letter, ie. ي -- it should be removed :))
(3) "it only had ممتيزة"
(4) "What is that final ة?"
This letter is called as ta marbuTa, which has the "ta" ت sound when it is not at the end of spelling and it has the هْ "h" sound at the end of spelling.
Generally speaking, ta marbuTa is a sign of the feminine form (but not always). So, ممتازة means "amazing/excellent (fem.)" that describes a feminine noun.
(1) "I would like to find an explanation of the mistake"
As far as I know, the only way we get the explanation of the mistake is from the forum. So, you put some questions -- then wait from other members that can solve your problem.
(2) "Why I cannot see tips?"
Unfortunately, for Arabic, all tips are still not available from the app. We should open the tips from Duolingo site, www.duolingo.com, by using our web browser app. Click the respective "tree skill lesson" and the "tips" option will be popped up. Or, ... you can read the tips and notes from this link https://duome.eu/tips/en/ar
