Which of the following best describes the accepted form of communication in Martha's Vineyard?

The accepted form of communication in Martha's Vineyard is best described as sign language, primarily due to the historical context of the island where a significant number of Deaf residents existed for generations. The use of sign language in this community developed organically, leading to the creation of a unique sign language known as Martha's Vineyard Sign Language (MVSL). MVSL was a fully functional language used by both Deaf and hearing individuals, showcasing a blend of communication styles tailored to the community's needs.

In Martha's Vineyard, where Deafness was relatively common, sign language allowed for seamless interaction among residents, fostering an inclusive environment. Both Deaf and hearing individuals used sign language, indicating its central role in everyday communication on the island. This contrasts with the other options, as oral speaking, written communication, and gestural communication alone do not encompass the rich, interactive nature of the community's collective language practice. The prominence of sign language reflects the value placed on Deaf culture and identity within the historical context of Martha's Vineyard, making it the most accurate descriptor of the communication form used in this unique community.
