What is an onomy?

Could you clarify what exactly an "onomy" is? It's not a term that's commonly used in the context of cryptocurrency or finance. Are you perhaps referring to a specific branch of study or a concept related to economics or linguistics? If so, could you provide more context or examples to help me understand your question better? Alternatively, if you're looking for a term related to cryptocurrency or finance, perhaps you meant to ask about a specific aspect of the industry, such as tokenomics or blockchain technology?
