A striking example of an evil personality (7)
I believe the answer is:
lucifer
This clue could be a double definition.
'a striking example' is the first definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'an evil personality' is the second definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'of' acts as a link.
Can you help me to learn more?
(Other definitions for lucifer that I've seen before include "Evil spirit" , "Satan, the Dark Angel" , "Devil - match!" , "once a match for > Dickens" , "Rising star" .)
