What does American Sign Language primarily serve as for its users?

American Sign Language (ASL) primarily serves as a manual visual language, which is significant for its users because it allows individuals who are deaf or hard of hearing to communicate effectively through visual gestures, facial expressions, and body language. ASL is distinct in that it has its own grammar and syntax, which differs from spoken English. This visual modality makes it accessible to those who are unable to hear, enabling them to express complex ideas, emotions, and concepts in a fully expressive manner.

A written system or spoken language alternative does not capture the essence of ASL. Unlike options that imply ASL functions primarily as a text-based or auditory form of communication, recognizing it as a manual visual language emphasizes its reliance on visual-spatial elements rather than auditory cues. Additionally, categorizing ASL as assistive technology overlooks its role as a natural language that serves a cultural and communal purpose for the Deaf community rather than functioning as a tool to assist in communication.
