When you don't know something and want to gain knowledge about it, you often have to "study" it.  "To study" is to devote time and effort in order to gain knowledge.  The process of studying hopefully leads to actually gaining knowledge, and when you have gained knowledge, you have "learned" something.    Example:  "I want to learn algebra, so I study it every day."  

When you already know something and you are sharing your knowledge with someone else, you "teach" what you know.  You already know Arabic, so you are ready to "teach" it to someone else.
