How do you say ninja in ASL?

There's no single sign in American Sign Language (ASL) that translates directly to "ninja."

Instead, you would likely sign the concept of "ninja" using a combination of signs and expressions:

* "Secret Agent" (secret, agent): This sign combination gets at the stealthy and covert nature of a ninja.

* "Shadow" (shadow): This sign emphasizes the ninja's ability to move silently and unseen.

* "Warrior" (warrior): This sign acknowledges the ninja's fighting skills and training.

You could also use a combination of these signs, or incorporate descriptive signs like "black clothes" or "sword" to further clarify your meaning.

Ultimately, how you sign "ninja" in ASL depends on the context and your specific intention.
