Many arabic characters look identical, except for the dots. For most of arabic’s history, these did not exist- one character stood for many phonics. In some of these cases it is unclear which of the two parent characters are the true parent - influence was likely taken from both. Thus the characters have been put under the parent character with the most similar sound. ↩
