Translation:Rawad and Carrie
The audio is adding an -in ending here actually, which is a type of case inflection in Arabic. If you've studied Latin or German, this ending is equivalent to the dative and genitive cases. It also marks the noun as indefinite (specifically the -n does this). Names are commonly indefinite grammatically, because they don't come with the definite article "al-". It's not incorrect to have the -in here, but it's also not necessary, there's no context obliging "Rawaad" to be in the dative/genitive case (and foreign names like "Carrie" remain uninflected). So, the audio would probably be better as just "Rawaad wa-Karrii"
Two people on another thread, whom I believe are Arabic speakers, said the "-un" at the end of the proper noun (Carrie) is called "nunation" and in this case is the "-un" sound because it is the nominative case/subjective case and that this is done in MSA (as well as Classical Arabic).
"rawaadun wa kaarii" - if we follow Standard/Formal rules.
Nb: I got a downvote from Mr(s) Downvoter Without Any Feedback for a Legitimate Comment. Thanks so much! You have succeeded in making me lose the motivation to study! I know you're the best contributor. But, although you're the best in any Arabic course, this time... I will not delete my comment because of your downvote.
Or, please if you know that I have done something wrong, correct me! :))
It's not really teaching names. It's using names as an intermediate step between teaching the alphabet and teaching vocabulary. Since most Arabic vocabulary will be very unfamiliar to us, names are more familiar since they often occur in a range of languages.
But you're totally right about the various transliterations and spellings. That goes for both directions too, the Arabic names transliterated into English and the non-Arabic names transliterated into Arabic. I'm sure you can just suggest they add missing correct spellings.
You know from the other languages you've taken with Duolingo that when we get a new word, even if it hasn't been introduced by a picture, which most aren't, we always know what the word is, and how it is spelled, by putting our cursor over the word, whether the word is in English or the target language. Even if that were not so, it is not a tragedy for us to spell a word incorrectly, learn the correct spelling and do the sentence over again.
