Satan's team shedding a quiet tear, missing answer (7)
I believe the answer is:
tempter
'satan's' is the definition.
(I've seen this before)
'quiet tear missing answer' is the wordplay.
'quiet' becomes 'temp' (I am not sure about this - if you are sure you should believe this answer much more).
'missing' indicates named letters should be taken away.
'answer' becomes 'a' (abbreviation eg in Q and A).
'tear' with 'a' removed is 'ter'.
'temp'+'ter'='TEMPTER'
'team shedding a' is the link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for tempter that I've seen before include "Siren" , "seducer" , "Satan" , "Enticer" , "One offering enticements" .)
