Unveiled female personal assistant (4)
I believe the answer is:
aide
'personal assistant' is the definition.
(I've seen this before)
'unveiled female' is the wordplay.
'unveiled' says to take the centre (the word\'s outer letters are taken off).
'female' becomes 'maiden' (a young woman).
The centre of 'maiden' is 'AIDE'.
(Other definitions for aide that I've seen before include "Right-hand man/woman" , "Confidential assistant or advisor" , "Officer's assistant" , "Leader's assistant" , "one helping" .)
