Sign languages do not linguistically correlate to spoken languages but rather to the geographical location or nation where it is taught to the deaf.

The signs are often arbitrary, conventional and usually do not have a visual correlation to the underlying object or action just as spoken languages are not always onomatopoeic (representing related sounds).

Unlike spoken language, which involves transmission of linear stream of sounds, the sign language exploits the visual perception for the simultaneous processing of a variety of hues of information.
