Using the prefix "be-"?

I read somewhere that the prefix be- can be used as a causative and this got me thinking. Does this mean that because means to cause to cause or to make cause?


Solution 1:

From OED (the other one):

because

c.1300, bi cause "by cause," modeled on Fr. par cause. Originally a phrase, often followed by a subordinate clause introduced by that or why. One word from c.1400. As an adverb from late 14c.
