Another word for sign language is gesture language.
Sign language is primarily used by individuals who are deaf or hard of hearing, as well as by others in various communicative contexts. It consists of hand symbols, facial expressions, and body movements to convey meaning. The term ‘gesture language’ highlights its reliance on physical movements for communication. While ‘gesture language’ can refer to any system of communication using gestures, it’s often used interchangeably with sign language in a broader sense.
