learn sign language

Language is a human ability that is used to communicate with other humans with signs, whether or not movement.

While sign language is a language that uses more on body language, lip movements, and hand or finger movements.

Sign language is commonly used in deaf people due to damaged or malfunctioning of the auditory sense so it is necessary to have non-verbal language in the form of hand or finger signals in order to communicate with both deaf people and people in general.
