late Old English byldan "construct a house," verb form of bold "house," from Proto-Germanic *buthlam (cf. Old Saxon bodl, Old Frisian bodel "building, house"), from PIE *bhu- "to dwell," from root *bheue- "to be, exist, grow" (see be). Rare in Old English; in Middle English it won out over more common Old English timbran (see timber). Modern spelling is unexplained. Figurative use from mid-15c. Of physical things other than buildings from late 16c. Related: Builded (archaic); built; building.
In the United States, this verb is used with much more latitude than in England. There, as Fennimore Cooper puts it, everything is BUILT. The priest BUILDS up a flock; the speculator a fortune; the lawyer a reputation; the landlord a town; and the tailor, as in England, BUILDS up a suit of clothes. A fire is BUILT instead of made, and the expression is even extended to individuals, to be BUILT being used with the meaning of formed. [Farmer, "Slang and Its Analogues," 1890]
"style of construction," 1660s, from build (v.). Earlier in this sense was built (1610s). Meaning "physical construction and fitness of a person" attested by 1981. Earliest sense, now obsolete, was "a building" (early 14c.).
To prepare someone for swindling, extortion, etc; SET someone UP (1920s+ Underworld)
[first noun sense perhaps influenced by earlier build, ''the look and shape of tailored clothing'']
human body shape and physique type. The term somatotype is used in the system of classification of human physical types developed by U.S. psychologist W.H. Sheldon. In Sheldon's system, human beings can be classified as to body build in terms of three extreme body types: endomorphic, or round, fat type; mesomorphic, or muscular type; and ectomorphic, or slim, linear type. A somatotype number of three digits is determined for an individual classified by the system, with the first digit referring to endomorphy, the second to mesomorphy, and the third to ectomorphy; each digit is on a scale of one to seven. Hence the extreme endomorph has the somatotype 711, the extreme mesomorph 171, and the extreme ectomorph 117. The classification numbers are negatively correlated, so that a high number in one class precludes high numbers in the others; in practice, extreme types (711, 171, 117) are rare or nonexistent, and the person of normal build has a somatotype approaching 444, evenly balanced between extremes. See also ectomorph; endomorph; mesomorph.
