The term "deaf-and-dumb alphabet" is considered outdated and offensive in certain contexts, as it implies that individuals who are deaf or hard of hearing are unable to communicate effectively. Several synonyms have emerged over the years to replace this term, including manual alphabet, finger alphabet, and sign language alphabet. These terms emphasize the use of hand gestures and visual communication in place of spoken words. Other terms, such as American Sign Language (ASL) fingerspelling and manual communication system, highlight the specific language system used by deaf and hard of hearing individuals. These synonyms are more inclusive and respectful of individuals with hearing disabilities.
