decentralization

Etymology

It is formed from English decentralize + -ation,^[2] or, as Etymonline analyses it, from de- and centralization.^[3] Merriam-Webster Unabridged and Webster's Third take it as probably from French décentralisation, from décentraliser.^[4] The OED compares the French noun, which it dates to 1829,^[2] while Etymonline finds German Decentralisation by 1835, with reference to France, and says the word does not seem to appear in French before the earliest English records.^[3] The verb decentralize is recorded from 1829 and is formed from the same prefix and centralize, compared by the OED with the French verb, recorded from 1821 or earlier;^[2] Etymonline and Barnhart instead suggest it may be a back-formation from the noun.^[3][5] The noun centralization itself goes back to 1797 and was first used of the concentration of power in Napoleonic France, on the model of French centralisation.^[2][3]

Earliest recorded meaning

The action or process of moving control away from a central authority: 1831, in the Morning Post of 2 December.^[2] The 1989 edition of the OED dated the word 1846, as do Merriam-Webster and Barnhart,^[6][7][5] and Etymonline gives 1839.^[3]

Semantic evolution

The word began in politics: Etymonline's first sense is the removal of local functions of government from the immediate control of a central authority,^[3] and the 1989 edition of the OED described it as especially the weakening of the central authority and the distribution of its functions among local bodies.^[6] The revised OED defines it more widely, as the transfer of control over planning and management from a central body to smaller units, so that it now applies to businesses and other organizations as well as governments.^[2] Merriam-Webster also records a second sense, the movement of population and industry out of city centres to suburbs and outlying areas.^[4][7]
