Immediately returns to collect top lawyer in cart (5)
I believe the answer is:
wagon
'cart' is the definition.
(I've seen this in another clue)
'immediately returns to collect top lawyer' is the wordplay.
'immediately' becomes 'now' (I've seen this in another clue).
'returns' is a reversal indicator.
'to collect' indicates putting letters inside (inserted letters are collected by others).
'top lawyer' becomes 'ag' (I can't explain this - if you can you should believe this answer much more).
'now' reversed gives 'won'.
'won' going around 'ag' is 'WAGON'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for wagon that I've seen before include "Freight truck" , "Trailer, railway truck" , "Railway freight vehicle" , "Vehicle for transporting goods" , "Horse-drawn vehicle" .)
