I want to know the answer to the following question:
What is occasionally written with two characters that contain the same radical?
All the background I'm provided with is that "– originally written as 批把 with the hand radical, referring to the down and up strokes when playing this instrument, which was then changed to 枇杷 (tree radical), which is still used for the fruit, while the character was changed to 琵琶 when referring to the instrument.". Is that enough to answer the question?
Answer: no
