Outspoken article by GB Shaw (7)
I believe the answer is:
candida
'gb shaw' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'outspoken article by' is the wordplay.
'outspoken' becomes 'candid' (synonyms).
'article' becomes 'a' (the indefinite article in English).
'by' is a charade indicator (letters next to each other).
'candid'+'a'='CANDIDA'
Can you help me to learn more?
(Other definitions for candida that I've seen before include "GBS play" , "by G.B. Shaw" , "Parasite" , "Fungus" .)
