Block off border with sharp spikes (6)
I believe the answer is:
barbed
'block off border with sharp spikes' is the definition.
I can't judge whether this definition defines the answer.
'block off border' is the wordplay.
'block off' becomes 'bar' (synonyms).
'border' becomes 'bed' (a flower bed is the border of a garden).
'bar'+'bed'='BARBED'
Can you help me to learn more?
(Other definitions for barbed that I've seen before include "Pointed or wounding, words or wire" , "Having projecting points, perhaps wire" , "(Of wire) having short spikes at intervals" , "Wounding, spiteful" , "Thorny - cutting" .)
