self-reinforcing

The term is a modern compound adjective formed within English by combining established morphemes. The core concept originates from the verb "reinforce," a 15th-century borrowing from French meaning to strengthen with additional support. The prefix "self-" directs the action inward, creating a reflexive sense. The Latin-derived prefix "re-" adds the crucial dimension of repetition or cyclical action. Thus, the literal construction "self-again-strengthening" logically evolves to describe any system where an initial effect produces changes that amplify the effect itself, creating a feedback loop, a concept central to systems theory, economics, and behavioral psychology.

Structure: self (own) + re (again) + inforcing (making stronger) self: From Old English 'self', 'seolf', 'sylf', meaning "own, same." It functions as a prefix denoting something directed at or originating from oneself. re: A prefix from Latin 're-', meaning "again, back." It indicates repetition or return to a previous state. inforcing: Derived from the verb 'enforce', which comes from Old French 'enforcier' (to strengthen, force), built from Latin 'in-' (in, into) + 'fortis' (strong). In this compound, it functions as the core meaning of making something stronger.
