Iconicity, the relationship between form of speech and its content, provides an important clue on shape formation mechanism of words.
Far from being a marginal verbal kind of play, Iconicity is a basic principle of
live speech, and more generally of natural languages.
Iconicity emphasises the speakers’ “creative energies”. It is not just characteristic of an earlier, more primitive stage of language, but it plays a role whenever a speaker’s (or a writer’s) expressivity is at issue: when, for whatever reason (poetic, practical, humorous, out of sheer necessity), he or she is trying lo express himself or herself anew, in a more concrete or less worn-down form of language.
