Origin and history of interrupt

early 14c., "corrupted, debased in character," from Old French corropt "unhealthy, corrupt; uncouth" (of language) and directly from Latin corruptus, past participle of corrumpere "to destroy; spoil," figuratively "corrupt, seduce, bribe," from assimilated form of com-, here perhaps an intensive prefix (see com-), + rup-, past participle stem of rumpere "to break," from a nasalized form of PIE *runp- "to break" (source also of Sanskrit rupya- "to suffer from a stomach-ache;" Old English reofan "to break, tear").

Meaning "decomposing, putrid, spoiled" is from late 14c. Sense of "changed for the worse, debased by admixture or alteration" (of language, etc.) is from late 14c. Meaning "guilty of dishonesty involving bribery" is from late 14c. Related: Corruptly; corruptness.

late 14c., in medicine, "act of bursting or breaking," in reference to a vessel, etc. of the body, from Old French rupture and directly from Latin ruptura "the breaking (of a vein), fracture (of an arm or leg)," from past-participle stem of rumpere "to break" (from PIE root *runp- "to break;" see corrupt (adj.)).

Specifically as "abdominal hernia" from early 15c. The sense of "breach of friendly relations or concord" is by 1580s; the general sense of "act or fact of breaking or bursting" is by 1640s. Rupturewort (1590s) was held to be efficacious in treating hernias, etc.
