However, human language is structured and language must have meaningful rule-governed patterns of sounds, letters, and words (Jay 3). Obviously, there are no letters or words in elephant communication, but do the sounds follow a structured pattern? Human language is special in the sense that placing words in random order will not result in a meaningful sentence. An elephant will emit a specific growl twelve times in half an hour in order to express that it wants to go in a certain direction, while facing in that direction (acoustic communication). Although this is an indication of communication, it is not an indication of structure. The elephant may emit different calls in different orders, while expressing the same idea: that there is a predator nearby or that there is intentional direction..
