There isn't a single sign for "went" in ASL. Instead, the sign for "go" is used along with a sign indicating the past tense.
Here's how you would sign "went":
1. Sign "GO": The sign for "go" is made by starting with your dominant hand in a "5" handshape (all fingers extended and spread) at your forehead, then moving the hand forward in a straight line.
2. Sign "PAST": There are a few ways to indicate the past tense, but the most common is to add a slight flick of the wrist at the end of the sign for "go".
So, you would combine these two signs to sign "went":
* "GO" (with a flick of the wrist at the end)
Important Note: The specific sign for "go" can vary slightly depending on the context and regional variations. It's best to learn from a qualified ASL instructor to ensure you're using the correct signs and movements.
