The relation between structural markedness and funniness ratings (A), iconicity ratings (B), and funniness and iconicity together (C), in a set of 1.419 English words. Each dot represents 14 or 15 words. Solid line with smoothed mean shows cumulative markedness. Other lines show relative prevalence of complex onsets (flap), codas (clunk), and verbal diminutives (drizzle). Higher structural markedness goes together with higher iconicity and funniness ratings. This supports the theory of structural markedness as a metacommunicative cue.
