Hi, this is my first time posting here.
I really love studying using this site for my english learning.
well, i have a question...
what is the difference between "because" and "because of"???
if anyone can teach me this, it will helps me so much.
"Because" is a conjunction and "because of" is a preposition, which means you have to use a clause after "because", but you have to use a noun or noun phrase after "because of". For example, you say "I am tired because I worked hard, or I am tired because of my hard working. You cannot say "I am tired because my hard working", nor can you say "I am tired because of I worked hard". Hope this helps.
