for these three characteristics of language: arbitrariness, displacement, and productivity we have to explain what would happen to our language if we lose one of these characteristics.

Question

ie. what would our language obtain, how would our communication be affected, and wat type of statements would we no longer be able to produce?

For Arbitrarieness, we would obtain much more diagrams and drawings, and language would be much more schematic. Communication would be affected because it would be too basic and childish.
and we would no longer be able to make hand gestures or statements such as "what's up"

Without Displacement, language would be very bland and always current.
not sure how communication would be affected as a whole
we wouldn't be able to make statements that refer to the past or future, like what did you do last weekend, or what do you have planned next weekend?

I'm not sure about productivity either..

please help and proofread my work..
