peril

peril: [13] Etymologically, peril means a ‘trying out of something’, an ‘experiment’. The word comes via Old French peril from Latin perīculum ‘experiment, danger’, a noun formed from the base *per- ‘attempt’ (which also lies behind English empiric, experience, expert, pirate, and repertory). Its derivative perīculōsus originally reached English via Old French as perilous [13], but subsequently became contracted to parlous [14].
