Big character from Leeds United boxing with a coach (6)
I believe the answer is:
landau
'big character from leeds united' is the definition.
I can't tell whether this definition defines the answer.
'boxing with a coach' is the wordplay.
'boxing' means one lot of letters goes inside another ('box' can mean contain, as in to put in a box).
'with' becomes 'and'.
'coach' becomes 'lu' (I am not sure about this - if you are sure you should believe this answer much more).
'and'+'a'='anda'
'anda' inserted within 'lu' is 'LANDAU'.
Can you help me to learn more?
(Other definitions for landau that I've seen before include "Four-wheeled vehicle with two folding hoods" , "A four-wheel covered carriage" , "Old-fashioned four-wheeled covered carriage" , "Horse-drawn, folded-top carriage" , "Old four-wheeled covered carriage" .)
