Same way u have learnt other language. learnng of language is a process that once should put effort achieve level knowledge in gradual prcess by taking time., there is no short cut for that. spoken, written, and reading these three skills varies in effort to acquire some proficiency. If u just want to talk to people, you have to mingl with arabic people. Another approach is you can pay and learn from some institution offering arabic class. so good luck. It took for me 15 years to reach some satisfactory level of reading, and fluently to speak arabic. if u think to dedicate yourself for this noble task, then Good luck.
