I just discovered there are two tags makruh and makrooh. Neither are listed as having a tag synonym (makruh; makrooh). As far as I'm aware, these are just two transliterations of the same Arabic word.
Question: Can we synonymize the "makruh" and "makrooh" tags?
I'd suggest one myself, only I don't know which one is the best transliteration to choose. I'd guess the best is "makruh" because the of the Wikipedia page Makruh.
