* "Not" sign with a shake: This is the most common way to convey "none" in ASL. You make the "not" sign (palm facing forward, index finger extended, and shaking it side to side) and sometimes add a slight headshake.
* "Empty" sign: This sign can be used for "none" when referring to a container or space. The sign is made by making a "C" shape with your hand and moving it as if emptying a container.
* Specific sign for the category: You can use a sign for the specific category you're referring to. For example, if you are asking "Are there any apples?" and the answer is "none," you could sign "apple" then "not."
Example:
* Question: "Do you have any cookies?"
* Answer (using "not" with a shake): "Cookies?" (sign "cookies") "Not" (sign "not" with a shake).
Remember that sign language is visual and the context, facial expressions, and body language all play a role in conveying meaning.
