Bit of a walk -- Michael's got his Dizzy maybe following around (8)
I believe the answer is:
footstep
'michael's got his dizzy maybe following around' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'bit of a walk' is the wordplay.
'bit of' becomes 'foot' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'a walk' becomes 'step' (I've seen this before).
'foot'+'step'='FOOTSTEP'
Can you help me to learn more?
(Other definitions for footstep that I've seen before include "Sound of a step of someone walking" , "Sound of a pace" , "Sound of walker" , "Mark made when walking" .)
