Boat man at a car crossing (9)
I believe the answer is:
catamaran
'boat' is the definition.
(I know that catamaran is a type of boat)
'man at a car crossing' is the wordplay.
'man' becomes 'tama' (I can't justify this - if you can you should give a lot more credence to this answer).
'at' is a charade indicator (letters next to each other).
'a' becomes 'an'.
'crossing' means one lot of letters goes inside another (to cross can mean to go over or around).
'an' put after 'car' is 'caran'.
'tama' going into 'caran' is 'CATAMARAN'.
Can you help me to learn more?
(Other definitions for catamaran that I've seen before include "Boat with twin, parallel hulls" , "Twin-hulled craft" , "raft of logs" , "Vessel with paralleltwin hulls" , "Two-hulled boat" .)
