Weird pop artist left with Marilyn originally (10)
I believe the answer is:
paranormal
'weird' is the definition.
Both the definition and answer are adjectives. Perhaps you can see a link between them that I don't see?
'pop artist left with marilyn originally' is the wordplay.
'pop' becomes 'pa' (both can mean father).
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'left' becomes 'l' (common abbreviation).
'with' is a charade indicator (letters next to each other).
'marilyn originally' becomes 'norma' (I've seen this in another clue).
'l' put after 'norma' is 'normal'.
'pa'+'ra'+'normal'='PARANORMAL'
Can you help me to learn more?
(Other definitions for paranormal that I've seen before include "mystic" , "Supernatural" , "on a higher plane?" , "Beyond scientific understanding" , "Scientifically inexplicable" .)
