How to shelter border road initially? This'll do it (8)
I believe the answer is:
hedgerow
'this'll do it' is the definition.
I can't judge whether this defines the answer.
'how to shelter border road initially?' is the wordplay.
'to shelter' means one lot of letters goes inside another.
'border' becomes 'edge' (synonyms).
'initially?' indicates taking the first letters (I've seen 'initially' mean this).
The first letter of 'road' is 'r'.
'edge'+'r'='edger'
'how' placed around 'edger' is 'HEDGEROW'.
(Other definitions for hedgerow that I've seen before include "natural fence" , "Line of entwined bushes and trees" , "rural boundary" , "Living boundary between fields" , "Bushy boundary" .)
