Walk along canal with top hat wobbling (7)
I believe the answer is:
towpath
'walk' is the definition.
(thesaurus)
'with top hat wobbling' is the wordplay.
'with' becomes 'w' (abbreviation).
'wobbling' indicates anagramming the letters.
'w'+'top'+'hat'='wtophat'
'wtophat' with letters rearranged gives 'TOWPATH'.
'along canal' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for towpath that I've seen before include "Riverside walk" , "Track once used to pull barges on canals" , "Track beside a canal" , "Canal-side walkway" , "canal feature" .)
