autonomy

Borrowed from Ancient Greek αὐτονομῐ́ᾱ (autonomíā, “freedom to use its own laws, independence”), from αὐτόνομος (autónomos, “living under one's own laws, independent”) +‎ -ῐ́ᾱ (-íā, “-y, -ia”, nominal suffix). By surface analysis, auto- (“self”) +‎ -nomy (“a system of rules or laws about a particular field”).
