Slaver \SLAV-uhr\ or \SLAY-vuhr\ , intransitive verb;
1. To slobber; to drool
1. Saliva drooling from the mouth
This word dates to the early 14th century from Old Norse slafra ("to slaver") and it may be imitative in origin. Slobber is a little older (1400's) and is also of imitative origin, as are Frisian slobberje, Middle Late German slubberen, and Middle Dutch overslubberen, and more.
Today's word and the first definition were both taken from Dictionary.com's 'Word of the Day' for Sunday, May 22
