Something preventing access for awful bloke - cad (8)
I believe the answer is:
blockade
'something preventing access' is the definition.
I can't tell whether this definition defines the answer.
'awful bloke cad' is the wordplay.
'awful' indicates an anagram.
'bloke'+'cad'='blokecad'
'blokecad' is an anagram of 'BLOCKADE'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for blockade that I've seen before include "Obstruction of access, as to entry of goods" , "Isolation of place by sea" , "The sealing off a place to prevent entry or exist" , "Besiege" , "Barricade" .)
