American Sign Language: "arm"
Realistically, when discussing or interpreting the concept of 'ARM' in ASL it is rare to use a separate sign that would be glossed as 'ARM' and instead it is more common to simply depict the arm and/or what is happening to the arm. For example, an interpreter could fingerspell ARM (using fs-ARM) and then demonstrate (depict / mime) whatever the arm is doing or will be done to the arm.
