taxonomy
Animals and other organisms are classified within a succession of nested groups that ranges from the general to the particular.
In zoological taxonomy, the use of the suffix -inae for subfamily names is a matter of established scientific convention and formal code.1
This standardized ending is derived from the New Latin -īnae, which is the feminine plural form of the Latin suffix -īnus. By following these specific naming rules, zoologists ensure consistency across the classification of animals. These names are typically formed based on the type genus of the group.213
While these conventions help bring stability to biological nomenclature, it is important to note that such standardized endings are not universal across all branches of biology; for instance, botany and other fields have their own distinct taxonomic histories and naming traditions.1
