Way functions become reparations (9)
I believe the answer is:
roadworks
'reparations' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'way functions' is the wordplay.
'way' becomes 'road' (road is a kind of way).
'functions' becomes 'works' ('work' can be a synonym of 'function').
'road'+'works'='ROADWORKS'
'become' is the link.
Can you help me to learn more?
(Other definitions for roadworks that I've seen before include "Street repairs" , "They hold traveller up" , "holding up travellers" , "What delay motorists" , "reason for traffic hold-up" .)
