How do you say hello in sign language?

You can't say "hello" in sign language because it's not a single sign. Sign languages use visual and gestural communication, so the concept of "hello" is conveyed differently depending on the context and the specific sign language.

Here are some ways to greet someone in American Sign Language (ASL), the most common sign language in the United States:

* "Good morning": The sign for "good morning" is made by bringing your dominant hand up to your forehead and then sweeping it down in front of you.

* "Good afternoon": The sign for "good afternoon" is made by bringing your dominant hand up to your chin and then sweeping it down in front of you.

* "Good evening": The sign for "good evening" is made by bringing your dominant hand up to your chest and then sweeping it down in front of you.

* "Hello" in a more casual setting: You can use a wave or a simple nod.

It's important to remember that different sign languages have different signs and expressions. If you are interested in learning ASL, there are many resources available online and in your community.
