"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.
