Oprah tied knot - she was divine (9)
I believe the answer is:
aphrodite
'she was divine' is the definition.
I can't tell whether this definition defines the answer.
'oprah tied knot' is the wordplay.
'knot' indicates anagramming the letters (I've seen 'knotted' mean this).
'oprah'+'tied'='oprahtied'
'oprahtied' is an anagram of 'APHRODITE'.
Can you help me to learn more?
(Other definitions for aphrodite that I've seen before include "got Paris's approval" , "Greek goddess of beauty and love" , "Greek goddess equivalent to Roman Venus" , "Sex goddess" , "Greek version of Roman Venus" .)
