A female repeatedly publicises romantic liaisons (7)
I believe the answer is:
affairs
'romantic liaisons' is the definition.
'affairs' can be an answer for 'liaisons' ('affair' can be a synonym of 'liaison'). I'm not certain of the 'romantic' bit.
'a female repeatedly publicises' is the wordplay.
'female' becomes 'f' (abbreviation).
'repeatedly' says to double the letters.
'publicises' becomes 'airs' (airing is a kind of publicizing).
'f' doubled is 'ff'.
'a'+'ff'+'airs'='AFFAIRS'
(Other definitions for affairs that I've seen before include "Business and financial dealings" , "Business; amours" , "Current ones are of interest to the public" .)
