constitutive

Etymology

It is borrowed from Medieval Latin *cōnstitūtīvus,^[2][3] a form the OED calls a Latin type, perhaps medieval,^[3] from the participial stem of Latin cōnstituō (“to cause to stand, set up, establish”),^[2][3] from com- and statuō (“to set”),^[2] from Proto-Indo-European *sta- (“to stand, make or be firm”).^[2] The Shorter Oxford records cōnstitūtīvus (“confirmatory, defining”) as Late Latin,^[4] while the Dictionary.com Unabridged analyses the word as constitute plus -ive.^[5] The form French constitutif is in Cotgrave's dictionary of 1611.^[3]

Earliest recorded meaning

Having the power to establish something or to give it a formal, definite existence: 1592, in William West's Symbolæography,^[3][6] Etymonline dates the word to about 1600.^[2]

Semantic evolution

From the idea of establishing, the adjective moved within a generation to what makes a thing what it is: Bishop Hall used it for "essential" in 1610,^[3] and before 1640 it could also describe any part that goes to make up a whole, so that it overlapped with constituent.^[3][7] Johnson (1755) gives both "elemental; essential; productive" and "having the power to enact or establish".^[8] The legal and political side narrowed in 1682 to the power of appointing to an office.^[3] A noun use, "a constituent part", lasted only from 1647 to 1697.^[3] The modern technical uses come from the second group of senses: in Kantian philosophy the word is contrasted with regulative,^[6] in chemistry it describes a property that depends on the arrangement of atoms in a molecule,^[7][6] and since 1932 biochemists have used it of an enzyme produced continuously, whatever the cell's needs.^[3][7]
