Conj. because, because;
When because and for are used as "because", their usage differences are:
1 and because indicate the direct reason, which is usually unknown to the listener and has the strongest tone. It is often used to answer why questions, usually after the main clause, or it can exist alone.
For example:
(1) I stayed at home because it rained. I stayed at home because of the rain.
Because Lingling was ill, she didn "t come to school. Lingling didn't go to school because of illness.
(3)Why is she absent? Why is she absent? Because she is sick. Because she is ill.
Besides, in emphasizing sentence patterns, only because can be used.
For example:
It was because I missed the early bus that I was late for school. I was late for school because I missed the early bus.
2. When used as a conjunction, for is similar to because, but the reason it expresses often provides the situation that has not been explained above. for does not mean the direct reason, but indicates the reason for addition or inference, so for is regarded as an isometric conjunction, and the clause it guides can only be placed at the back of the sentence (or become a sentence alone), and the logical relationship between the two clauses before and after is not necessarily causal, which is separated by commas, and for cannot be placed at the beginning of the sentence.
For example:
(1) The days are short, for it is now December. The days are short, because it is December.
(2) It must have rained, for the ground is wet. (It is speculated that it rained from the "wet ground", but the wet ground is not necessarily becaused by rain, and for cannot be changed to cause.)
(3) The ground is wet because it has been rained. ("Rain" is the direct cause of "wet ground".)
When there is a certain causal relationship between the two clauses before and after (sometimes it is difficult to distinguish between direct cause and speculative cause), for and cause can be used interchangeably. For example:
I could not go, for/because I was ill. (5) He felt no fear, for/because he was a brave boy. He was not afraid, because he was a brave boy.
