Etymology

Origin of kiss

before 900; Middle English kissen to kiss, Old English cyssan (cognate with German küssen, Old Norse kyssa ), derivative of Old English coss a kiss; cognate with Old Norse koss, German Küss

Explanation

To kiss is to touch someone's face or lips with your own lips. Most people kiss each other as a way of saying "Hello!" or because they love each other. You might kiss your grandma on the cheek, kiss your girlfriend on the mouth, or kiss your dog on his furry head. In each case, you're using an ancient human practice that anthropologists believe evolved either from a basic instinct, or perhaps from the habit of mothers feeding their babies pre-chewed food, mouth-to-mouth. Colloquially, you can "kiss something goodbye," or accept the fact that you'll lose it — and "the kiss of death" is something sure to bring failure.
