Judicial review is through: way to receive pardon for Spaniard (7)
I believe the answer is:
inquest
'pardon for spaniard' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'judicial review is through way to receive' is the wordplay.
'judicial review' becomes 'que' (I can't explain this - if you can you should believe this answer much more).
'is through' becomes 'in'.
'way' becomes 'st' (abbreviation for street).
'to receive' means one lot of letters goes inside another.
'in'+'st'='inst'
'que' placed within 'inst' is 'INQUEST'.
Can you help me to learn more?
(Other definitions for inquest that I've seen before include "Judicial investigation to determine facts about a death" , "Coroner's court" , "Coroner's jury" , "Process overseen by coroner" , "hearing" .)
