Sign language is a visual-gestural language used by deaf and hard-of-hearing individuals for communication. It is a complete and complex system of language that relies on visual-manual modality to convey meaning.

It can be provided either simultaneously or consecutively, using in-person or remote methods.

It plays a vital role in different settings, including events, meetings, legal proceedings, and other scenarios, ensuring the inclusion and accessibility of deaf and hard of hearing individuals as a priority.

It is important to note that all countries have their unique sign language. For instance: ASL (American Sign Language), which is used in the United States.
