Fingerspelling is a method used in sign language to represent letters of the alphabet using hand shapes. It allows individuals to spell out words that do not have a specific sign, such as names or technical terms. Each letter corresponds to a unique hand position, making it a visual way to communicate. In American Sign Language (ASL), fingerspelling is commonly used alongside signs to enhance understanding. The manual alphabet is the foundation of fingerspelling, where each letter is formed by specific hand configurations. This technique is essential for effective communication within the deaf and hard-of-hearing communities.
