The dictionary says that a kiss is "a salute made by touching with the lips pressed closely together and suddenly parting them." From this it is quite obvious that, although a dictionary-may know something about words, it knows nothing about kissing.
If we are to get the real meaning of the word kiss, instead of going to the old fogies who compile dictionaries, we should go to the poets who still have the hot blood of youth coursing in their veins. For, instance, Coleridge called a kiss, "nectar breathing." Shakespeare says that a kiss is -a "seal of love. Martial, that old Roman poet who hid ample opportunity to do research work on the subject, says that a kiss was "the fragrance of balsam extracted- from aromatic trees; the rise odor yielded by the teeming saffron; the perfume of fruits mellowing in their winter buds; the flowery meadows in the summer; amber warmed by the hand of a girl; a bouquet of flowers that attracts the bees."
