Someone emailed me this image. He was extending the regel of the chof pshuta since it was a bit short. In doing so he made a negiya. I told him that if the negiya was from beshaas ksivah it would be more of an issue as when making the mem stumah underneath he would have made it into a big nun / beis /chof. However since both letters were written in their entirety, and then the negiya was made, can it be fixed? Or is it a shinuy tzurah?
