Clear a path or build a road (4,3)
I believe the answer is:
make way
'clear a path' is the definition.
(I've seen this in another clue)
'build a road' is the wordplay.
'build' becomes 'make' (synonyms).
'a road' becomes 'way' (I've seen this in other clues).
'make'+'way'='MAKE WAY'
'or' is the link.
(Other definitions for make way that I've seen before include "Allow room (for something else)" , "What road builders do" , "Provide room for another" , "Clear a path" , "Clear a passage, provide space for" .)
