ASL is Contextual: ASL relies heavily on context and facial expressions to convey meaning. Instead of a single sign, you'd use a combination of signs and expressions to express the idea.
How to Sign "I'll Be Back":
1. Sign "RETURN": Make a "C" handshape and move it back and forth in front of your chest, as if you're drawing a line back and forth.
2. Sign "LATER": Make a "5" handshape and move it down and away from your face, as if you're waving goodbye.
3. Facial Expression: A slight smile or nod could emphasize the idea of "coming back" rather than leaving forever.
Example:
* You could sign "RETURN" and "LATER" together with a slight smile, indicating that you'll be back later.
Important Note: The specific signs and expressions you use could vary depending on the context of the conversation and the individual signer's style.
