"I do not know his neighbor Maha."
Translation:لا أَعْرِف جارَتهُ مَها.
If you mean in the sense of "kennen" and "wissen" in German, then yes kinda there is. Usually if you are talking about facts, info of any kind, then you can use the verb (أعرف: A3rif) or (أعلم:A3lam). However, if you are talking about knowing a person, then you cannot use (أعلم:A3lam). So, you can say that (ِأعرف:A3rif) is more general in the sense of knowing.
