Pray, Sir, said he to the Bard, after thrusting his Tongue into a Corner of his Cheek, and rolling his Eyes at Miss Willis, (Tricks which he had caught by endeavouring to take off a celebrated Comedian) were these fine Tragedies of yours ever acted?

wake (v.): "to become awake," a Middle English merger of Old English wacan "to become awake, arise, be born, originate," and Old English wacian "to be or remain awake," both from Proto-Germanic *waken (cognates: Old Saxon wakon, Old Norse vaka, Danish vaage, Old Frisian waka, Dutch waken, Old High German wahhen, German wachen "to be awake," Gothic wakan "to watch"), from PIE root *weg- (2) "to be strong, be lively" (cognates: Sanskrit vajah "force, strength; swiftness, speed," vajayati "drives on;" Latin vigil "watchful, awake," vigere "be lively, thrive," velox "fast, lively," vegere "to enliven;" vigil "awake, wakeful," vigor "liveliness, activity"). Causative sense "to rouse from sleep" is attested from c. 1300. Related: Waked; waking.
