When there's no sign for a name or a new word, ASL signers spell it letter by letter with hand shapes. Fingerspelling is the manual alphabet — the bridge for names, brands, and anything not yet a sign.
A language you can see
American Sign Language (ASL) is a full language expressed with the hands, face, and body — not English on the hands. Fingerspelling uses a handshape for each letter of the alphabet, and it is used mainly for names and words that have no set sign.
Beginners should fingerspell slowly and clearly. Hold your hand steady near your shoulder and form each letter fully — accuracy matters more than speed.
