superstructure

Etymology

It is formed from English super- + structure.^{[2][3][4][5][6][7]} Merriam-Webster Unabridged traces it instead to Latin superstructus, the past participle of superstruō (“to build on or over”), from super- and struō (“to build”), with -ure added in English.^[8] The OED compares the earlier nouns superstruction and superstructive.^[2] Its Marxist sense follows German Überbau (“structure of society above its economic base”), used by Marx by 1859 and literally the part of a building above its foundation,^[2] and its geological sense follows Oberbau (“upper structure”), used in 1935 by C. E. Wegmann.^[2]

Earliest recorded meaning

An immaterial structure, as of thought or action, built on something else as a foundation: 1626, in A. C.'s True Relations of Sundry Conferences.^[2][8] Etymonline dates the word to the 1640s, in the literal sense of a structure built on something else.^[4]

Semantic evolution

The figurative use is recorded about twenty years before the literal one,^[2] which first appears in 1645, in James Howell's Epistolae Ho-Elianae, for a building or upper part of a building resting on a foundation.^[2] Johnson (1755) defined it as that which is raised or built upon something else, and his quotations are mostly figurative: Tillotson called purgatory a superstructure upon the Christian religion.^[6] Engineering and shipbuilding gave it new uses: in 1830 for the track, sleepers and fittings of a railway as opposed to its roadbed, and since 1835 for the parts of a ship built above the hull and main deck.^[2][8] In 1887 the English translation of Engels by Samuel Moore and Edward Aveling used it for the Marxist idea of the institutions and culture that rest on a society's economic base.^[2] Twentieth-century science added senses in crystallography (1931), geology (1937) and biochemistry (1952), the last for the higher-order three-dimensional structure of a protein or nucleic acid.^[2]
