More civil one left to reflect, say, on leading domestic rapper? (11)
I believe the answer is:
poltergeist
'leading domestic rapper?' is the definition.
'poltergeist' can be an answer for 'rapper?' (I've seen this in another clue). I am not certain of the 'leading domestic' bit.
'more civil one left to reflect say' is the wordplay.
'more civil' becomes 'politer' (I've seen this in another clue).
'one' becomes 'i' (Roman numeral).
'left' suggests deleting specific letters (some letters have left).
'to reflect say' becomes 'geist' (I can't explain this - if you can you should give a lot more credence to this answer).
'politer' with 'i' taken out is 'polter'.
'polter'+'geist'='POLTERGEIST'
'on' is the link.
Can you help me to learn more?
(Other definitions for poltergeist that I've seen before include "Noisy spook" , "Ghost that makes strange noises and disorders furniture" , "Mischievous ghost" , "Active ghost" , "disruptive presence" .)
