I have continued the other deck for Arabic on Duolingo and will keep adding cards. There is no audio.
Full diacritics (short vowels, doubling of consonants, ...) is provided, except:
- ال, which makes a word definite is usually written without the َ , so it's المَلِك in stead of أَلْمَلِك.
- when a consonant without diacritic is followed by ا ، ي، و these are used as long vowels. Eg. ري is pronounced rii, but رَي is pronounced as ray.
- the words are written in the pausal form, not the nominative. Eg. ملك، الملك, in stead of مَلِكٌ، المَلِكُ.
