What means adin in the definition of amok

[_Philippe]

In the GRE test 189 amok is defined as "adin a state of rage".
What means adin, I failed to find it in a dictionary.
Please explain.

I am not familiar with the existence of the word "adin." Anyone else?

However, "Mad; in a state of rage" would make sense. I think if you saw "adin" it was a typo. They do sometimes appear on exams (oops)!
