scandal: [16] Greek skándalon originally meant literally ‘trap’ (it came from prehistoric Indo- European *skand- ‘jump’, which also produced Latin scandere ‘climb’, source of English ascend, descend, and scan). It was extended metaphorically to ‘snare for the unwary, stumbling block’, and passed into late Latin as scandalum, which was used for ‘cause of offence’. It came down to Old French as escandle, which was not only the source of a short-lived Middle English scandle, but also lies behind English slander. It was the later French form scandale that gave English scandal.
