What does the suffix nomy mean in taxonomy?

The suffix "-nomy" in "taxonomy" comes from the Greek word νόμος (nomos), which means "law" or "rule".

So, "taxonomy" literally translates to "the law of arrangement". This reflects the core concept of taxonomy: the science of classifying organisms according to a set of rules and principles.

Think of it as establishing a system of rules for organizing and naming living things, much like a legal code governs a society.
