4 come to make a great sacrifice (8)
I believe the answer is:
hecatomb
'great sacrifice' is the definition.
(I've seen this before)
'4 come to make a' is the wordplay.
I cannot really see how this works, but
'to' is within the answer.
'a' is found in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for hecatomb that I've seen before include "Large-scale sacrifice" , "great public sacrifice" , "mass slaughter" , "Great quantity of victims" , "sacrifice victims" .)
