Note car on motorway going downhill and uphill (5)
I believe the answer is:
minim
'note' is the definition.
(musical note)
'car on motorway going downhill and uphill' is the wordplay.
I cannot quite understand how this works, but
'car' could be 'mini' (Mini Cooper) and 'mini' is present in the answer.
'motorway' could be 'm' and 'm' is found within the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for minim that I've seen before include "A note in music, half as long as a semi-breve- it's a palindrome" , "Musical note - small amount of liquid" , "Palindromic note" , "Half-note" , "Two crotchets in one" .)
