Chinese characters
Occasionally a bisyllabic word is written with two characters that contain the same radical, as in Hu Die  hudie "butterfly", where both characters have the insect radical Chong . A notable example is pipa (a Chinese lute, also a fruit, the loquat, of similar shape) - originally written as Pi Ba  with the hand radical, referring to the down and up strokes when playing this instrument, which was then changed to Pi Pa  (tree radical), which is still used for the fruit, while the character was changed to Pi Pa  when referring to the instrument. In other cases a compound word may coincidentally share a radical without this being meaningful.
