Help incorporating standard article shows discrimination (9)
I believe the answer is:
apartheid
'discrimination' is the definition.
(thesaurus)
'help incorporating standard article' is the wordplay.
'help' becomes 'aid' ('aid' can be a synonym of 'help'**).
'incorporating' means one lot of letters goes inside another.
'standard' becomes 'par' (I've seen this before).
'article' becomes 'the' (the 'definite article' part of speech).
'par'+'the'='parthe'
'aid' enclosing 'parthe' is 'APARTHEID'.
'shows' acts as a link.
(Other definitions for apartheid that I've seen before include "South Africa's former social policy - hit parade (anag)" , "Social policy of racial segregation" , "form of rule" , "former South African segregation system" , "Network of bars no longer" .)
