Finger alphabets, also known as finger spelling or manual alphabet, is the use of hand gestures and fingers to represent letters or words. Synonyms for finger alphabets include dactylology, sign language, finger language, hand alphabet, manual communication, and manualism.
Dactylology is a specific form of finger spelling used in sign language. Sign language, on the other hand, is a language that primarily uses visual gestures and facial expressions to communicate. Finger language and hand alphabet are also often used interchangeably with finger alphabets to refer to the same concepts.
Manual communication is a broader term that encompasses all forms of communication using gestures and body language, including sign language and finger spelling. Manualism refers to the use of sign language or other manual communication as a means of communication for the deaf or hard of hearing.
