vigil: [13] Etymologically, to take part in a vigil, you have to be ‘alert’ and ‘awake’. The word comes via Old French vigile from Latin vigilia, which was derived from the adjective vigil ‘awake, alert’, so the notion underlying it is of staying awake to keep watch. Another derivative of the Latin adjective was vigilāre ‘keep watch’, which lies behind English reveille [17], surveillance [19], vigilant [15], and vigilante [19] (via Spanish). It came ultimately from the Indo-European base *wog-, *weg- ‘be lively or active’, which also produced English vigour, wake and watch.
