Here's a breakdown:
1. "A" sign: Make a fist with your dominant hand and extend your thumb.
2. "ma" sign: Make a "C" shape with your dominant hand and move it back and forth slightly.
3. "zon" sign: Make a "5" handshape with your dominant hand and move it from your chin downwards.
You can sign these three signs consecutively to spell out "Amazon" in ASL.
However, keep in mind that there is no single, universally accepted sign for "Amazon" in ASL. Some people may use different signs or combinations of signs to represent the word.
