Go to visit fox? Abandon this fantasy! (4,4,2,5)
I believe the answer is:
come down to earth
'visit fox? abandon this fantasy' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'go to' is the wordplay.
I cannot really see how this works, but
'go' could be 'comedown' (coming down is a kind of going) and 'comedown' is located in the answer.
'to' is present in the answer.
The remaining letters 'earth' 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 come down to earth that I've seen before include "Astronauts must eventually" , "face reality" , "stop fantasising" .)
