Love to get about the town at speed (8)
I believe the answer is:
velocity
'speed' is the definition.
(I know that speed can be written as velocity)
'love to get about the town' is the wordplay.
'to get about' is an anagram indicator (I've seen 'getting about' mean this).
'the town' becomes 'city' (I've seen this in another clue).
'love' with letters rearranged gives 'velo'.
'velo'+'city'='VELOCITY'
'at' is the link.
(Other definitions for velocity that I've seen before include "Swiftness" , "Rate of movement." , "Agreeable -- Riviera resort" , "Distance travelled per unit of time" , "Rate of motion in a specified direction" .)
