Note: Knut's following the road from London to Leeds (5)
I believe the answer is:
minim
'london to leeds' is the definition.
I can't tell whether this defines the answer.
'note knut's following the road' is the wordplay.
'note' becomes 'n' (abbreviation).
'knut's' becomes 'I'm' (where the crossword setter is 'Knut').
'following' is a charade indicator (letters next to each other).
'the road' becomes 'MI' (resembles Mn motorway).
'n'+'im'='nim'
'nim' put after 'mi' is 'MINIM'.
'from' is the link.
Can you help me to learn more?
(Other definitions for minim that I've seen before include "Note equal to two crochets" , "Two crotchets in one" , "Note with value of half a semibreve" , "note or > dose" , "Beat" .)
