Study article about engaging socially acceptable chaperon (6)
I believe the answer is:
duenna
'chaperon' is the definition.
(duenna is a kind of chaperon)
'study article about engaging socially acceptable' is the wordplay.
'study' becomes 'den' (term for a study or office).
'article' becomes 'an' (indefinite article).
'about' says the letters should be written backwards.
'engaging' means one lot of letters goes inside another.
'socially acceptable' becomes 'u'.
'an' in reverse letter order is 'na'.
'den'+'na'='denna'
'denna' placed around 'u' is 'DUENNA'.
(Other definitions for duenna that I've seen before include "Woman chaperon in Hispanic countries" , "caring senora" , "(Spanish) chaperone" , "governess in Spain" , "mature escort" .)
