Manoeuvre train with sign of hesitation (8)
I believe the answer is:
engineer
'manoeuvre' is the definition.
(thesaurus)
'train with sign of hesitation' is the wordplay.
I cannot really see how this works, but
'hesitation' could be 'er' (sound used when hesitating) and 'er' is located in the answer.
The remaining letters 'engine' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for engineer that I've seen before include "Professional who uses scientific knowledge to solve practical problems" , "Person who uses scientific knowledge to solve practical problems" , "Bring about (an event); technologist" , "Operator of a railway locomotive" , "Designer of machinery, structures etc" .)
