Split into parts as below (7)
I believe the answer is:
asunder
'split' is the definition.
(I've seen this in another clue)
'as below' is the wordplay.
'below' becomes 'under' (synonyms).
'as'+'under'='ASUNDER'
'into parts' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for asunder that I've seen before include "Into parts or pieces" , "Apart (archaic)" , "(Torn) apart" , "(Split) into pieces" , "separately" .)
