Origin: ῥήσσω (hrace'-so) both prolonged forms of ῥήκω (which appears only in certain forms, and is itself probably a strengthened form of ἄγνυμι (see in 2608)) to "break," "wreck" or "crack", i.e. (especially) to sunder (by separation of the parts; 2608 being its intensive (with the preposition in composition), and 2352 a shattering to minute fragments; but not a reduction to the constituent particles, like 3089) or disrupt, lacerate
