Here's a breakdown:
* Sign language is a visual language that uses hand gestures, facial expressions, and body language to convey meaning.
* Finger spelling is a part of sign language where individual letters are formed with the hand to spell out words, names, or specific terms.
* Deaf and hard of hearing individuals rely on sign language, including finger spelling, as a primary means of communication.
While hearing individuals might learn finger spelling to communicate with Deaf people, it is primarily a part of the Deaf community's language and culture.
