Tricks for mastery

Useful tips to understand the difference between confusing words "Because", "Since".

1. 'Because' is used primarily to introduce a reason or cause, emphasizing the direct reason behind an action or event.

2. 'Since' can introduce both reasons and time. As a reason, it's often softer or implies a more longstanding or assumed cause. As a time indicator, it denotes when a particular situation began or an action took place.

3. 'Because' is a more direct way of stating a reason and can be seen as more emphatic. It is straightforward and can be used in both formal and informal contexts.

4. Using 'since' to indicate a reason can sometimes sound more formal or nuanced. It may imply that the reason is already known or somewhat evident
