Class of wage earners making it a real port (11)
I believe the answer is:
proletariat
'class of wage earners' is the definition.
'proletariat' can be an answer for 'class' (proletariat is a kind of class). I'm not certain of the 'of wage earners' bit.
'making it a real port' is the wordplay.
'making' indicates anagramming the letters.
'it'+'a'+'real'+'port'='itarealport'
'itarealport' is an anagram of 'PROLETARIAT'.
Can you help me to learn more?
(Other definitions for proletariat that I've seen before include "The lower orders" , "The people; workers" , "Marx's wage-earning class" , "Working-class people" , "The working class" .)
