1. "Night" as a general concept:
* The most common sign is made by touching your forehead with your index finger, then moving your hand down to your chin in a sweeping motion. This sign is similar to the sign for "sleep".
2. "Good night":
* This is signed by making the sign for "sleep" and then bringing your hand to your cheek, as if you are tucking someone in.
3. "Night" as a specific time of day:
* You can use the sign for "night" (explained above) and then add the sign for the specific time. For example, to sign "8 o'clock at night," you would sign the number "8" and then the sign for "night."
4. "Last night":
* This is signed by making the sign for "night" and then pointing to the back of your head, as if you are referring to the past.
It's important to note that the specific signs for "night" can vary slightly depending on the signer's region and personal style.
If you're learning ASL, it's always best to check with a qualified instructor to learn the correct signs for your specific area.
