Pronunciation

  • UK: /ˌəʊvəˈləʊd/, /ˈəʊvəˌləʊd/[1]
  • US: /ˌoʊvɚˈloʊd/, /ˈoʊvɚˌloʊd/[1]

Etymology

It is formed from English over- + load.[2][3][4][5][6][7] The verb comes first, from load the verb; the noun is from load the noun.[2][3] Middle English had overladen in the same sense,[3][8] the source of overladen.[3] An Old English noun oferlād (“a carrying across, translation”), modelled on Latin translātio, is recorded in the Durham Ritual;[2][9] the OED treats it as an early, obsolete sense of the noun.[2]

Earliest recorded meaning

To load with too heavy a burden or cargo: 1553, in Thomas Wilson's Arte of Rhetorique;[2] Etymonline dates it to the 1550s.[3]

Semantic evolution

The verb was used from the start of loads and cargoes, and also of overcharging a gun and, figuratively, of burdening the mind;[2] Johnson (1755) defined it as "to burthen with too much", with a quotation about a child's memory "charged and over-loaded".[7] The noun, an excessive load or burden, followed in 1645.[2][3] Electrical engineering gave it new senses: the verb of subjecting a circuit to too great a current in 1889, and the noun of an excessive current in 1904.[2][3] The intransitive use, to become overloaded, is dated 1932 by the OED[2] and 1961 by Etymonline.[3] Compounds such as information overload and sensory overload extend the figurative noun.[1]
