1. Using a descriptor sign:
* "Scary" as in "frightening": You can combine the signs for "fear" (sign: make a fist with your dominant hand and shake it slightly at your chest) and "make" (sign: make a "C" shape with your dominant hand and move it forward and slightly down).
* "Scary" as in "spooky": You can use the sign for "ghost" (sign: make a "C" shape with your dominant hand and move it back and forth in front of your face) and then add the sign for "like" (sign: touch your thumb to your chin and move your hand out).
2. Using a mime:
You can act out being scared, such as by making a scared face, shaking your head, or covering your eyes.
3. Using a combination of signs:
You can combine signs for different aspects of "scary", such as "fear", "danger", or "unknown".
4. Using context:
You can use facial expressions and other context clues to convey that something is scary.
Here are some examples of how you might sign "scary" in different contexts:
* "The movie was scary." You might sign "movie" then "fear" (shaking your fist at your chest) or "ghost" (making a "C" shape and moving it back and forth).
* "I'm scared of the dark." You might sign "I" then "fear" (shaking your fist at your chest) and then "dark".
* "The haunted house was scary." You might sign "haunted" then "house" then "ghost" (making a "C" shape and moving it back and forth) and then "like" (touching your thumb to your chin).
It's important to note that ASL is a visual language, so practice signing these phrases with a teacher or native speaker to get the nuances right.
