smiling

the word 'smiling' is a modern english derivative formed from the verb 'smile' with the addition of the suffix '-ing'. the root 'smile' itself entered middle english from a germanic source, likely related to the middle high german 'smielen', meaning to smile. while its ultimate pre-germanic origin is obscure, it is part of a cluster of words in germanic languages expressing a quiet or restrained expression of pleasure. the suffix '-ing' is a prolific english morphological device inherited from old english, used to form present participles and gerunds, thus transforming the action into a descriptive adjective or a noun denoting the act itself. the combination logically and transparently yields the concept of 'engaged in or characterized by the act of smiling'.
