Sure! Here are the definitions for the last two relationships:
Item/category relationship
This is when a specific item is classified under a broader category. For example, "a rose is a type of flower" demonstrates how a particular item (rose) fits into the broader category (flower).
Part/whole relationship
This involves a part being a component of a larger whole. For example, "a wheel is a part of a bicycle" highlights how the wheel is a necessary component that contributes to the functioning of the larger object (bicycle).
