Fast transport for a quiet country road (5)
I believe the answer is:
plane
'fast transport' is the definition.
'plane' can be an answer for 'transport' (plane is a kind of transport). I am not sure about the 'fast' bit.
'quiet country road' is the wordplay.
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'country road' becomes 'lane' (I've seen this before).
'p'+'lane'='PLANE'
'for a' is the link.
Can you help me to learn more?
(Other definitions for plane that I've seen before include "Nepal (anag.)" , "What imitates bird" , "Tool for smoothing wood" , "Flat surface; tree" , "Tree - figure - aircraft" .)
