As Because Since and For

Because puts more emphasis on the reason, and most often introduces new information which is not known to the listener/reader.
Because I was ill for six months, I lost my job.
When the reason is the most important part of the sentence, the because- clause usually comes at the end. It can also stand alone. Since and as cannot be used like this.
  • Why am I leaving? I’m leaving because I’m fed up!
(NOT …I’m leaving since/as I’m fed up!)
  • Why are you laughing? – Because you look so funny.
A because- clause can be used at the end of a sentence to say how one knows something.
You didn’t tell me the truth, because I found the money in your room. (= …I know because I found…)FOR
For introduces new information, but suggests that the reason is given as an afterthought. A for- clause could almost be in brackets. For- clauses never come at the beginning of sentences, and cannot stand alone. For, used in this sense, is most common in a formal written style.

  • I decided to stop and have lunch – for I was feeling hungry.
