What is the main purpose of using fingerspelling in sign language?

The main purpose of using fingerspelling in sign language is to supplement signs for unfamiliar words, making it particularly useful when introducing names, technical terms, or words that do not have a designated sign within the sign language lexicon. Fingerspelling allows for the communication of specific words that may not have an established sign, providing clarity and ensuring that the intended message is conveyed accurately.

This practice enhances communication by allowing the signer to bridge the gap between vocabulary limitations and the recipient's understanding. It's an essential tool that complements existing signs rather than replacing them or confusing the message. Fingerspelling works best in conjunction with other signed language features, allowing for a richer and more versatile form of communication.
