Regarding only child reversing Range Rover? (5)
I believe the answer is:
bison
'range rover?' is the definition.
(I've seen this in another clue)
'regarding only child reversing' is the wordplay.
I cannot really see how this works, but
'regarding' could be 'on' (on or regarding a particular topic) and 'on' is located in the answer.
The remaining letters 'bis' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for bison that I've seen before include "Ox-like ruminant" , "US prairie cattle" , "O bins could be full of buffalo" , "Buffalo (US)" , "It's a buffalo in America" .)
