The word 'unification' is a direct borrowing from Late Latin 'unificationem', the noun of action from the verb 'unificare', meaning "to make one". This Latin verb is itself a compound, built from the root 'uni-' (one) and '-ficare' (to make). The core semantic logic has remained remarkably stable from its ancient origins to its modern usage: it literally means "the act of making into one". This concept was applied in medieval Latin to theological contexts, such as the union of divine and human natures, before broadening in Modern English to describe any process of bringing separate entities into a single, coherent whole, whether in politics, science, or logic.
