Carter's work — a huge construction outside Los Angeles (7)
I believe the answer is:
haulage
'carter's work' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'a huge construction outside los angeles' is the wordplay.
'construction' indicates anagramming the letters (answer constructed from certain letters).
'outside' indicates putting letters inside (some letters go outside others).
'los angeles' becomes 'LA' (abbreviation).
'a'+'huge'='ahuge'
'ahuge' anagrammed gives 'hauge'.
'hauge' enclosing 'la' is 'HAULAGE'.
Can you help me to learn more?
(Other definitions for haulage that I've seen before include "Transport business" , "Commercial transportation of goods" , "Commercial transport of goods" , "Road transport" , "Transportation of heavy goods" .)
