Dove, one perched on hand after uplifting eclipse (8)
I believe the answer is:
pacifist
'dove' is the definition.
(I've seen this in another clue)
'one perched on hand after uplifting eclipse' is the wordplay.
I cannot quite see how this works, but
'one' could be 'i' (Roman numeral) and 'i' is located in the answer.
'hand' could be 'fist' (hand curled into a fist) and 'fist' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for pacifist that I've seen before include "One will seek an end to war" , "Believer in non-violence" , "War opponent" , "One refusing military service" , "Person opposed to war" .)
