Standard statement of support for barrier (8)
I believe the answer is:
stockade
'for barrier' is the definition.
(I've seen this before)
'standard statement of support' is the wordplay.
'standard' becomes 'stock' (synonyms).
'statement of support' becomes 'ade' (I am not sure about this - if you are sure you should believe this answer much more).
'stock'+'ade'='STOCKADE'
Can you help me to learn more?
(Other definitions for stockade that I've seen before include "Strange dock seat in this type of imprisonmment" , "defensive structure" , "Cod steak consumed in enclosure as for military prisoners" , "Defensive fence of stout posts" , "Defensive barrier of upright posts" .)
