义 (Kangxi radical 3,丶+2, 3 strokes,cangjie input戈大 (IK) or難戈大 (XIK),composition⿶乂丶)
Derived from乂. Originally乂 was borrowed because of homophony and being mostly displaced by (刈). Later, to avoid confusion a stroke was added on top of乂 to distinguish correctly. Now a homophonic character; compare舊 →旧
