I’m one mixed up with a lot of passion (9)
I believe the answer is:
emotional
'i'm one mixed up with a lot of passion' is the definition.
I can't tell whether this defines the answer.
'i'm one mixed up with a lot' is the wordplay.
'mixed up with' indicates anagramming the letters.
'im'+'one'='imone'
'a'+'lot'='alot'
'imone' with its letters anagrammed with 'alot' gives 'EMOTIONAL'.
Can you help me to learn more?
(Other definitions for emotional that I've seen before include "Moving" , "Impassioned - excitable" , "Touching" , "Arousing intense feelings" , "Characterized by intense feeling" .)
