disruptive

Etymology

It is formed from English disrupt + -ive,^[2][3][4][5] or, as the OED puts it, from the participial stem Latin disrupt- with -ive.^[6] The verb disrupt is from disruptus, the past participle of disrumpō (“to break apart, shatter”), formed from dis- (“apart”) and rumpō (“to break”).^[2][7][6] Etymonline thinks the electrical sense probably came from the French.^[2]

Earliest recorded meaning

Of an electrical discharge, breaking through an insulating medium: from 1840 in Etymonline,^[2] 1842–43 in the first edition of the OED,^[8] and 1855, in W. R. Grove, in the current OED.^[6] Dictionary.com dates the word to 1835–45.^[5]

Semantic evolution

The verb disrupt was hardly used before the 19th century,^[6][2] and the adjective began as a scientific term for electrical discharges.^[2][6] The general sense, "causing or tending to cause disruption", is recorded from 1862,^[6][2] and in geology "produced by disruption, eruptive" from 1876.^[6][2] In zoology since 1919 it has described coloration that breaks up the outline of an animal, a sense also used of camouflage.^[6] Its modern use is chiefly of people and actions that disturb order, as in disruptive behaviour.^[9][3]
