Because vs. Since: What's the Difference?

Because and since are conjunctions used to introduce subordinate clauses, but they differ in their usage and the emphasis they carry. Because is typically used to indicate a direct cause and effect relationship, strongly emphasizing the reason behind an action. On the other hand, since tends to suggest a time element and can provide reasoning that is less forcefully tied to an event, often indicating that the reasoning is already well known or presupposed.
