Etimologie (Engels)

From Middle English wakyr, from Old English wacor, waccor (“watchful, vigilant”), from Proto-West Germanic *wakr, from Proto-Germanic *wakraz (“awake, watchful”), equivalent to wake + -er.
Cognate with Scots wakir (“watchful”), Dutch wakker (“awake”), German wacker (“awake, alert, capable, brave”), Swedish vacker (“wakeful, watchful, fair, comely”). Also precisely cognate with Sanskrit वज्र (vájra, “adamantine”), both ultimately from Proto-Indo-European *wóǵ-ros (“strong, lively”), and therefore a doublet of vajra. Further related through the same Indo-European root to vigil, vigor, and vegetable.
