義肢

1. Origins, structure, and basic meaning

• Structure: 義肢 is read as ぎし; 義 adds the sense of an artificial replacement to 肢 (limb), producing “prosthetic limb.”
• Basic usage: Use 軽い素材の義肢 for material properties and 利用者に合わせて義肢を調整する for user-specific fitting.

2. Common pitfalls and similar expressions

• Arms and legs
  • It is broader than 義足, which specifically denotes a prosthetic leg, and can include replacement arms or legs.
• Display item and fitted device
  • An exhibition presents the lightweight material, while actual use requires a technician to adjust the limb to the user.
