"a rending asunder, a bursting apart, forcible separation into parts," early 15c., originally medical, "laceration of tissue," general sense from 1640s, from Medieval Latin disruptionem (nominative disruptio) "a breaking asunder," noun of action from past-participle stem of Latin disrumpere "break apart, split, shatter, break to pieces," from dis- "apart" (see dis-) + rumpere "to break," from PIE root *runp- "to break" (see corrupt (adj.)).
"break or burst asunder, separate forcibly." 1650s, but rare before c. 1820, from Latin disruptus, past participle of disrumpere "break apart, split, shatter, break to pieces," from dis- "apart" (see dis-) + rumpere "to break," from PIE root *runp- "to break" (see corrupt (adj.)). Or perhaps a back-formation from disruption. Earlier was disrump (1580s). Related: Disrupted; disrupting.
"disruption or destruction of order, a breaking up of order or system, absence of orderly arrangement," 1790, noun of action or state from disorganize.
"a breaking asunder, a violent disruption," 1829, from Latinized form of Greek kataklasm "breakage," from kata "down" (see cata-) + klan,klaein "to break," which is perhaps from PIE *kla-, variant of root *kel- "to strike" (see holt), but more likely of uncertain origin [Beekes]. Related: Cataclastic, in geology, in reference to a structural character due to intense crushing, 1885.
