Carriage reserved for small charge? (12)
I believe the answer is:
perambulator
'carriage' is the definition.
(perambulator is a kind of carriage)
'reserved for small charge?' is the wordplay.
I cannot really understand how this works, but
'for' could be 'to' (eg both can mean 'in the opinion of') and 'to' is present in the answer.
'charge?' could be 'ram' (I've seen this in other clues) and 'ram' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for perambulator that I've seen before include "Baby carrier (usually abbreviated)" , "Baby carriage" , "Baby's transport" .)
