The man from the Ministry of Transport? (3)
I believe the answer is:
tom
'the man' is the definition.
(Tom is a man's name)
'the ministry of transport?' is the wordplay.
'the' becomes 't' (the is pronounced as a 't' sound in some dialects).
'ministry of transport?' becomes 'om' (I can't explain this - if you can you should give a lot more credence to this answer).
't'+'om'='TOM'
'from' is the link.
Can you help me to learn more?
(Other definitions for tom that I've seen before include "Man's name; male cat" , "A male domestic cat" , "Very small person" , "Male feline" , "Cruise" .)
