Here's why:
* Noun: The noun sign is typically made with a double movement to emphasize its identity as a noun. This movement is called "redoubled" or "iterative.
* Verb: The verb sign is usually made with a single, fluid movement. This movement conveys the action of the verb.
Example:
* "Book" (noun): The sign for "book" is made with a double movement, opening and closing the hand twice.
* "Read" (verb): The sign for "read" is made with a single movement, sliding your index finger across your open palm.
Therefore, the correct statement is: In Noun-Verb pairs in ASL, the noun has two movements and the verb has one movement.
