The kanji character 非 is a pictographic character. It is composed of two parts: a radical on the left side, which may depict a bird's wings, and the character 三 (san - three) on the right. 三 (san) originally represented a set of connected things, in this case, a set of birds. The whole character 非 originally depicted birds flying in opposite directions, suggesting disagreement or opposition. Over time, the character evolved to represent negation, opposition, or incorrectness.
