This is how you sign Iceberg in American Sign Language.

To sign "Iceberg" in American Sign Language (ASL), start with both hands in a fist, palms facing each other, and make a bump movement. Then, transition to both fists with palms facing down, with the dominant hand tapping the top of the non-dominant hand. Finally, change both handshapes into a relaxed "5" with palms facing down, as if releasing something on your side, and end with handshapes in a claw, palms facing down. This sequence illustrates the concept of an iceberg.
