Introduction
Hi, I'm Duc. Today I want to share a grammar topic that comes up quite often in TOEIC: how to tell the difference between because, since, and as. These are very common linking words, but they're easy to mix up. I'll walk you through the nuances and usage of each one with concrete examples drawn from ETS 2024.

1. Definitions and Usage
Because
Because is used to express a cause or reason. When you want to explain why something happened, because is your go-to word. It's the most direct and straightforward of the three.
Example:
The meeting was canceled because of bad weather.
Since
Since can indicate either a point in time or a reason, and it carries a slightly more formal tone than because. When you want to emphasize a reason that has been in effect from a specific moment up to the present, since is the right choice.
Example:
We have been waiting here since noon.
As
As can also express a reason, and its level of formality is similar to since. It tends to appear in written English or in more formal contexts where you want to state a reason in a softer, less emphatic way.
Example:
As it was raining, the event was postponed.
2. Nuance Analysis
When distinguishing between because, since, and as, I've found that the differences lie not just in how they're used, but in the context surrounding them.
