Displacement

Definition:

In linguistics, a characteristic of language that allows users to talk about things and events other than those occurring in the here and now.
Displacement is one of the distinct properties of human language. Its significance as one of the 13 (later 16) "design features of language" was noted by American linguist Charles Hockett in 1960.

Examples and Observations:

• "When your pet cat comes home and stands at your feet calling meow, you are likely to understand this message as relating to that immediate time and place. If you ask your cat where it has been and what it has been up to, you'll probably get the same meow response. Animal communication seems to be designed exclusively for this moment, here and now. It cannot effectively be used to relate events that are far removed in time and place. When your dog says GRRR, it means GRRR, right now, because dogs don't seem to be capable of communicating GRRR, last night, over in the park. In contrast, human language users are normally capable of producing messages equivalent to GRRR, last night, over in the park, and then going on to say In fact, I'll be going back tomorrow for some more. Humans can refer to past and future time. This property of human language is called displacement. . . . Indeed, displacement allows us to talk about things and places (e.g. angels, fairies, Santa Claus, Superman, heaven, hell) whose existence we cannot even be sure of."
  
  
• A Characteristic of All Human Languages
  "Consider the range of things that you can say, such as a sentence like this:

Hey, kids, your mother left last night, but don't worry, she'll be back when she's come to terms with the whole notion of mortality.

(This was said tongue in cheek by a friend, but it's a useful example.) By uttering certain sounds in a given order, the speaker of this sentence is addressing particular individuals (the kids), referring to a particular individual who isn't there (their mother), referring to times that are not the present (last night and whenever the mother comes to terms), and referring to abstract ideas (worry and mortality). Let me point out in particular that the ability to refer to things that are not physically present (objects here, and times) is known as displacement. Both displacement and the ability to refer to abstractions are common to all human languages."

Achieving Displacement
"Different languages accomplish displacement in different ways. English has a system of auxiliary verbs (e.g., will, was, were, had) and affixes (e.g., pre- in predates; -ed in dated) to signal when an event occurred relative to the moment of speaking or relative to other events."

• Displacement and the Origins of Language
  "Compare these:

There's a mosquito buzzing in my ear.
Nothing is more irritating than a buzzing sound.

In the first, there's a particular buzzing in the here and now. In the second, there may be, but there needn't be--I could say this in reacting to a story about something that happened years ago. In talking about symbolism and words, people often make far too much of arbitrariness--the absence of any relationship between a word's form and its meaning. . . . [W]hen it comes to how language began, displacement is a factor far more important than arbitrariness."
(Derek Bickerton, Adam's Tongue: How Humans Made Language, How Language Made Humans. Hill and Wang, 2009)


"[M]ental time travel is critical to language. . . . Language . . . may have evolved primarily to enable humans to share their memories, plans, and stories, enhancing social cohension and creating a common culture."

• One Exception: The Dance of the Honeybee
  "This displacement, which we take utterly for granted, is one of the most momentous differences between human languages and the signalling systems of all other species. . . .
  
  "There is just one striking exception. A honeybee scout which has discovered a source of nectar returns to its hive and performs a dance, watched by other bees. This bee dance tells the watching bees what direction the nectar lies in, how far away it is, and how much nectar there is. And this is displacement: the dancing bee is passing on information about a site which it visited some time ago and which it now cannot see, and the watching bees respond by flying off to locate the nectar. Startling though it is, the bee dance is, so far at least, absolutely unique in the non-human world: no other creatures, not even apes, can communicate anything of the sort, and even the bee dance is severely limited in its expressive powers: it cannot cope with the slightest novelty."
