Pick out road material to acquire (6)
I believe the answer is:
target
'pick' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'road material to acquire' is the wordplay.
'road material' becomes 'tar' (I've seen this in another clue).
'to acquire' becomes 'get' ('get' can be a synonym of 'acquire').
'tar'+'get'='TARGET'
'out' acts as a link.
Can you help me to learn more?
(Other definitions for target that I've seen before include "Thing aimed at" , "Goal, objective" , "Aim, objective" , "Butt" , "Goal; victim" .)
