De-linkage is like a puzzle. Sometimes, different things are linked or connected together, just like puzzle pieces that fit perfectly. De-linkage is when we take those puzzle pieces apart and separate them.
In real life, de-linkage means separating things that were connected before. For example, schools and restaurants are connected because students go to school and then go eat at restaurants. But if we want to stop the spread of germs, we might need to de-link those things, which means closing down restaurants so students can't go there anymore.
Another example is when we think about the economy. Companies might be linked because they work together to make products. But sometimes, one company makes bad decisions that hurt the other companies. In that case, the other companies might need to "de-link" or disconnect from that one company to protect themselves.
De-linkage can be a good thing or a bad thing, depending on the situation. Sometimes, we need to separate things so that it's safer or better for everyone. But other times, it might make things harder or more complicated. It's like taking apart a puzzle and putting it back together again.
