I could be Moses, in spirit? (13)
I believe the answer is:
impressionist
'i' is the definition.
Although both the answer and definition are adjectives, I cannot understand how one could define the other.
'could be moses in spirit?' is the wordplay.
'could be' indicates anagramming the letters.
'moses'+'in'+'spirit'='mosesinspirit'
'mosesinspirit' anagrammed gives 'IMPRESSIONIST'.
Can you help me to learn more?
(Other definitions for impressionist that I've seen before include "One who takes off others" , "Mimic" , "Person pretending to be another" , "artist?" , "Is he taking off" .)
