Piece published by Conservative in article (7)
I believe the answer is:
tranche
'piece' is the definition.
Both the definition and answer are singular nouns.
Perhaps they are linked in a way I don't understand?
'published by conservative in article' is the wordplay.
'published' becomes 'ran' (running is a kind of publishing).
'by' is a charade indicator (letters next to each other).
'conservative' becomes 'C' (UK political abbreviation).
'in' indicates putting letters inside.
'article' becomes 'the' (the definite article in English).
'ran'+'c'='ranc'
'ranc' put into 'the' is 'TRANCHE'.
Can you help me to learn more?
(Other definitions for tranche that I've seen before include "Slice (of income)" , "issue of shares, perhaps" , "Share -- chanter (anag)" , "batch supplied" , "Part of the loan" .)
