effectuate

Etymology

It is borrowed from Medieval Latin effectuō (“to effect, bring about”), through its past participle effectuātus.^{[2][3][4][5][6]} The OED, in its 2008 revision, finds the Medieval Latin verb in a 14th-century British source, and allows that the English word may instead be formed independently from Latin effectus (“effect”) and -ate,^[7] probably after Middle French effectuer, recorded in the 15th century as affectuer.^[7] Etymonline derives it from French effectuer and that Latin noun, and reports the OED's view that it was modelled on actuate;^[8] Klein likewise treats it as formed on the analogy of the French verb.^[9] The Latin noun comes from the past participle stem of efficiō (“to work out, accomplish”), from ex- (“out”) and faciō (“to make, do”), from Proto-Indo-European *dhe- (“to set, put”).^[8]

Earliest recorded meaning

To bring to pass, accomplish: Etymonline and Dictionary.com date the verb to the 1570s,^[8][4] and Merriam-Webster Unabridged to 1580.^[2] The OED's first quotation is from Sidney's Arcadia, written before 1586 and printed in 1590.^[7]

Semantic evolution

The meaning has barely moved.^[7][10] Johnson (1755), quoting Sidney on "a fit instrument to effectuate his desire", defined it as to bring to pass or fulfil,^[10] and the OED speaks of carrying an intention or desire into effect.^[7] Merriam-Webster Unabridged illustrates the current use with a settlement in F. D. Roosevelt and with changes made by the courts in B. N. Cardozo.^[2] The past-participial adjective effectuate, brought about, also spelled affectuate, was used from 1584 to 1694.^[7]
