Instead, you would likely sign the concept of destiny using a combination of signs, depending on the specific context. Here are some options:
* "Fate" + "Decided": This would be a common way to express "destiny" as an unchangeable force. You would sign "fate" (which has a sign with a twist of the wrist) and then "decide" (sign for "decide" looks like a decision being made with the hand).
* "Future" + "Set": You could also use "future" and "set" to convey the idea of a predetermined course. "Future" is signed by pointing forward and "set" is signed by making a flat hand and bringing it down.
* "Something" + "Have to happen": This is a more general way to express destiny as an inevitability. "Something" is signed by making a question mark with your hand, and "have to happen" is signed by making a small circle with your index finger and thumb.
Remember that ASL is a visual language, so context and facial expressions are important for conveying meaning. For example, if you were talking about a person's destiny, you might also sign "them" or "person" to clarify.
You could also use a sign for a specific concept related to destiny, such as "fate", "fateful", "predetermined", or "inevitable", if those are more relevant to your meaning.
The best way to express "destiny" in ASL will depend on the specific situation and your personal interpretation of the word.
