Oddly safe in coach without one change (8)
I believe the answer is:
transfer
'change' is the definition.
(transfer is a kind of change)
'oddly safe in coach without one' is the wordplay.
I cannot really understand how this works, but
'one' could be 'an' (I've seen this in other clues) and 'an' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for transfer that I've seen before include "Carry over" , "Change (from one thing to another)" , "Hand, move, change, over" , "Give over!" , "a side to side movement in soccer, perhaps" .)
