Sly bard gets round secure barrier (9)
I believe the answer is:
roadblock
'barrier' is the definition.
(I know that barrier can be written as roadblock)
'sly bard gets round secure' is the wordplay.
I cannot quite see how this works, but
'round' could be 'o' (o is a circular letter) and 'o' is found within the answer.
an anagram of 'bard' is 'radb' which is located in the left over letters.
'secure' could be 'lock' (locking is a kind of securing) and 'lock' is present in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for roadblock that I've seen before include "Paving stone" , "put in place by police after fugitive" , "Barrier to traffic" , "Barrier constructed by police" , "Barrier on way" .)
