أبٌ

[prero]

What is the meaning of this?

[WaseemJohn]

These: ُ ِ ً ْ ّ ٍ ٌ َ play significant role in the pronounciation and they change based on the place of a word in a sentence. For example: if you start the sentence with a noun: the pen: القلمُ pronounced 'Alqalamu'. If it's object then القلمَ 'Alqalama' and if following a proposition then: القلمِ 'Alqalami' etc. But don't panic you don't need that info to speak or communicate in general, it's just very proper grammar that most Arabs hate hahaha
