What is translation for 或作譈懟，亦書作憞 ? In the sentence from the Kang-Xi Dictionary 或作譈懟，亦書作憞, I looked up
the characters 譈,懟,憞 all are pronounced  dui4 and all  are translated as to hate. I am confused  and do not know how to deal with this sentence. I am not sure, but those 3 charaters does not strike me as commonly used characters, or do they ?
或作譈懟，亦書作憞 means "also, it is identified to 譈 or 懟; and it can be written as 憞."
They are all archaic words and no longer used today. Neither orally nor literally.
