What happens during lexicalization?

Lexicalization refers to the process by which a finger-spelled sequence transforms into a sign that has a specific meaning and usage within a sign language. This is an important concept in the development of sign languages; it allows for more fluid and efficient communication as fingerspelled words (often representing English vocabulary) evolve into unique signs that are recognized as part of the lexicon of the sign language.

In this context, the option describing this transformation reflects the core idea of lexicalization, showcasing how language adapts and evolves over time, facilitating smoother communication among its users. While other options involve significant aspects of linguistic expression, they do not encapsulate the essence of lexicalization in the same way as the transformation of fingerspelled words into established signs does.
