100 in clear section of road is perhaps working for many? (9)
I believe the answer is:
freelance
'perhaps working for many?' is the definition.
(freelancing is a type of working)
'100 in clear section of road' is the wordplay.
'100' becomes 'c' (roman numeral).
'in' indicates putting letters inside.
'clear' becomes 'free' (synonyms).
'section of road' becomes 'lane'.
'free'+'lane'='freelane'
'c' going into 'freelane' is 'FREELANCE'.
'is' acts as a link.
(Other definitions for freelance that I've seen before include "Self-employed worker for hire" , "Writer or artist who sells services to different employers" , "not regularly employed" , "Self-employed person offering services where needed" , "Medieval mercenary" .)
