Give ground for road construction (4,3)
I believe the answer is:
make way
'construction' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.
'give ground for road' is the wordplay.
I cannot quite understand how this works, but
'give' could be 'make' (synonyms) and 'make' is present in the answer.
'road' could be 'way' (I've seen this in other clues) and 'way' is present in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for make way that I've seen before include "Stand back!" , "Allow room (for something else)" , "Provide room for another" , "'Allow room for someone else (4,3)'" , "Clear a path" .)
