Arabic is a beautiful language. Especially and mainly the standard Arabic.
Back in 2002 with all the hype of the wars in the Middle-East and watching documentaries about the conflict in Palestine,Iraq,
Afghanistan and elsewhere,I became interested in learning Arabic. Of course,I had also started listening to Arabic pop and used to buy CDs wherever I could find them.
I managed to learn how to write Arabic on my own,as well as the numbers,some grammar and some words and phrases.
Then in the mid-2000s,I found a teacher here and I had lessons for about two years. But I've forgotten a lot since then...
Now,should Arabic be a third official language for Pakistan? I don't know. It could be a choice language to learn at school,but maybe not official.
Then again,apart from being the language of the Quran,remember that it's a language spoken by hundreds of millions of people from Syria to Sudan and from the UAE and Oman to Morocco. And also by many people in Qomoros,Dzjibouti and maybe even Somalia and other central African countries.
That could give Pakistanis opportunities to work there or for trade,diplomacy or whatever else.
