What is alone in sign language?

There isn't one single sign for "alone" in American Sign Language (ASL). The sign used depends on the context and what you want to express. Here are some possibilities:

1. "Lonely" (with a sad expression): This sign is made by touching your thumb to your cheek and then moving your hand away, as if wiping away a tear.

2. "By oneself" (with a neutral expression): You can sign this by making a "C" handshape and tapping your chest twice.

3. "Isolate" (with a specific context): This sign involves making an "S" handshape and moving it outwards, as if pushing something away.

4. "Alone" (with a specific context): Depending on the context, you might use a combination of signs like "no" and then a sign for "people" or "company" to express being alone.

Important Note: Sign language is highly contextual. The meaning can change based on facial expressions, body language, and the context of the conversation. It's important to remember that there are often multiple ways to sign a concept in ASL, and the best sign to use will depend on the situation.
