well, the only thing i can think of is for you to learn the grammar of Arabic.
you'd also have to understand the word in its context. and i also suggest for you to learn how to write. this way, it sort of gives you a different look t the language, i know that sound weird but you'll know inshallah when you do it yourself. (sorry, im really bad at explaining things). i remember when i started to learn, i just got someone to read out three lettered words. then i would write them. thins is assuming that you know the basics of arabic.
