What does the term Soo refer to in Korean?

The term "Soo" in Korean specifically translates to "hand." It is often used in martial arts contexts to signify various techniques or movements that involve the hands. Understanding the significance of "Soo" is vital, as many techniques, strikes, and defenses in Korean martial arts, such as Taekwondo and Hapkido, are fundamentally derived from the use of the hands. This foundational knowledge assists practitioners in recognizing the importance of hand techniques in their overall training.

In contrast, the other options represent different body parts that have no relation to the term "Soo." For instance, while "Arm" refers to a broader limb incorporating the hand, "Neck" concerns another part of the body entirely, and "Waist" denotes the area around the lower abdomen. Each of these terms has distinct Korean equivalents, but they do not intersect with the definition of "Soo."
