systematics
Noun (used with a singular verb) 1. The scientific study and practice of classification, especially of organisms: Systematics is the branch of biology concerned with classifying organisms and determining their evolutionary relationships. It involves naming, describing, and organizing species into a coherent system. 2. The methodology or principles of systematic classification in any field: More broadly, it can refer to the principles and procedures for creating ordered systems of classification for any set of items or concepts.
Systematics is a singular noun (despite the "-ics" ending) and typically takes a singular verb (e.g., "Systematics is fundamental to biology"). It is primarily an academic and scientific term.
