How do you say boy in sign language?

You can't say "boy" in sign language with a single sign. Instead, you would sign "male" and then use a sign to indicate the age of the person you are referring to.

Here's how you could do it:

* For a young boy: Sign "male" and then sign "child."

* For an older boy/teenager: Sign "male" and then sign "teenager" or "young adult."

Remember, sign language can vary depending on the specific language you are using. There might be slight differences in the signs or the way they are used.
