Hello I'm learning english. I'd like to grasp the meaning of the prefix be- in verb building, in what way does it change the sense of the stem. It is said of befriend and belittle that the be- means "make or cause to be". I can figure them out as well as : betake oneself, befog, bestow... eventually befall. Belong does it cause you to long/yearn what is not yours? I don't get it very well. Neither do I with such verbs as : behave, behold. So my questions are : Do they all pertain to the rule? Help?
