1. REMEMBER: Make a "C" handshape and tap your forehead twice.
2. AGAIN: Make a "1" handshape, palm up, and move it back and forth in a slightly wavy motion.
You can combine these signs by signing "remember" first, then "again". This conveys the meaning of "reminding" or "remembering something again."
Important Note: ASL is a visual language, so seeing the signs being performed is essential for understanding them correctly. You can find videos demonstrating the sign for "reminding" on websites like YouTube or ASL dictionaries.
