Fast machine on a quiet country road (5)
I believe the answer is:
plane
'fast machine' is the definition.
'plane' can be an answer for 'machine' (plane is a kind of machine). I am not sure about the 'fast' bit.
'on a quiet country road' is the wordplay.
'on' says to put letters next to each other.
'a quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'country road' becomes 'lane' (I've seen this before).
'p' put next to 'lane' is 'PLANE'.
Can you help me to learn more?
(Other definitions for plane that I've seen before include "Smooth" , "Nepal (anag.)" , "Flat surface; tree" , "Tool for smoothing wood" , "Aircraft - level surface - carpenter's tool" .)
