reconstruct

Etymology

It is formed from English re- + construct.^{[2][3][4][5][6]} The OED compares French reconstruire (“to rebuild”), recorded in Middle French from 1549, and notes that the noun reconstruction is earlier.^[2] Construct is from Latin cōnstrūctus, the past participle of cōnstruō (“to pile up together, build”), from com- (“together”) and struō (“to pile up”).^[3]

Earliest recorded meaning

To construct or put together again, especially after damage or destruction: 1762, in T. Walter's New Mathematical Dictionary.^[2] Merriam-Webster also dates the verb to 1762,^[4] while Etymonline gives 1768 and Dictionary.com 1760–70.^[3][7]

Semantic evolution

From building again, the verb was extended to building again in the mind: to form a picture of a past event from assembled evidence, from 1838 in John Stuart Mill,^[2] 1862 in Etymonline.^[3] Police use, recreating the circumstances of a crime or accident to find its cause, is recorded from 1888,^[2][5] and in linguistics the verb has meant to deduce the forms of a protolanguage from the evidence of related languages since 1930.^[2][5] In the United States in 1863 it was used of restoring a Confederate state to the Union during Reconstruction, a sense now historical.^[2] Merriam-Webster adds the surgical sense of rebuilding an organ or part of the body.^[4]
