I recently learned about iteration marks, especially 々
. After reading the wikipedia article of iteration marks, I found the following text: "Further, if okurigana is present, then no iteration mark should be used, as in 休み休み. This is prescribed by the Japanese Ministry of Education in its 1981 Cabinet notification prescribes, rule #6—see okurigana article for elaboration."
now going to the wikipedia page of okurigana, the only thing that I can find about iteration marks is the following sentence: The 1981 Cabinet notification prescribes (通則6) the okurigana usage 次々 (iteration mark), but 休み休み (no iteration mark if okurigana is present).
Here it only gives an example, however it does not explain as why I am not allowed to use it.
So I wondered why it is not allowed to use iteration marks in okurigana. Why is 休み々ゝ
not allowed?
