Zany lass running round you, talking -- one circulates with food (4,5)
I believe the answer is:
lazy susan
'zany lass running' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'round you talking one circulates with food' is the wordplay.
I cannot really see how this works, but
'you' could be 'u' (I've seen this in other clues) and 'u' is found within the answer.
'one' could be 'an' (an apple is one apple) and 'an' is located in the answer.
'food' could be 'a' (A is an example) and 'a' is located in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for lazy susan that I've seen before include "circulates items for consumers" , "Revolving table stand" , "One spins around" , "Revolving tray on a dining table" , "Server" .)
