Word usage (for vs. because)

[27029450]

Could you let me know about what difference of usage between ”because” and ”for” which have the same meaning of reason.

To quote Michael Swan:

Because puts more emphasis on the reason, and most often introduces new information. When the reason is the most important part of the sentence, the because-clause usually comes at the end. It can also stand alone.

For introduces new information, but suggests that the reason is given as an afterthought. For-clauses never come at the beginning of sentences, and cannot stand alone. For used in this sense is a formal written style.

That about sums it up.

Just to add to what Mister Micawber said, I'd recommend not using for or as in this way when speaking. They're very unusual in speech.
