Logic of relatives is something we use to help us understand relationships between people, things, and ideas. It is like a map of connections between words, ideas, and people. We use it to make sure that when we talk about something, we are being consistent and that our ideas make sense. For example, when we are talking about our family, we use logic of relatives to understand how different family members are related to each other like how to mom is related to the brother or how the dad is related to the uncle. It helps us know who is who and how they are connected.
