Farm captured by despicable symbol of French tyranny (8)
I believe the answer is:
bastille
'symbol of french tyranny' is the definition.
The definition suggests a singular noun which matches the answer.
'farm captured by despicable' is the wordplay.
'farm' becomes 'till' (to till is to work on land).
'captured by' indicates putting letters inside.
'despicable' becomes 'base' (synonyms).
'till' going within 'base' is 'BASTILLE'.
Can you help me to learn more?
(Other definitions for bastille that I've seen before include "Paris prison, now opera" , "French fortress" , "Fastness" , "Paris prison destroyed at the start of the French Revolution" , "Notorious Paris prison stormed in French revolution" .)
