The idiom "double-edged sword" means something that has both positive and negative consequences. It is like a sword that has two sharp edges, which means it can cut both ways.
For example, let's say you get a promotion at work that comes with a higher salary but also more responsibilities. This situation is a double-edged sword because the extra money is good, but the extra work can be stressful and overwhelming.
Another example could be a social media platform. It can be a great way to connect with friends and family, but it can also be a source of negativity and cyberbullying. Therefore, social media is a double-edged sword.
In general, we use this idiom when we want to describe a situation that has both advantages and disadvantages. It is essential to weigh the pros and cons before making a decision.
