Would two like him be of one mind? (7)
I believe the answer is:
halfwit
'be of one mind?' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'would two like him' is the wordplay.
I cannot really see how this works, but
'him' could be 'wit' and 'wit' is found in the answer.
The remaining letters 'half' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for halfwit that I've seen before include "One only 50% all there?" , "Charlie?" , "dunce?" , "Mug" , "Idiot" .)
