Event delegation must be handled by an ancestor element.

When you use event delegation, the listener must be set on an element that is the parent or other "ancestor" element of the one that will trigger the event.

A sibling of a parent would not be in the direct ancestry line, so it would not receive an event propagating from the element in question.

What does it mean a sibling?

The word "sibling" means "having the same parent".

If we were talking about people instead of HTML elements, it would mean a brother or sister. And the "sibling of the parent" would be an aunt or uncle.
