Paramour (5)
I believe the answer is:
lover
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">paramour</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for lover that I've seen before include "Swain" , "I could be fickle" , "Paramour" , "fan" , "'Lady Chatterley's - - ' by D H Lawrence" .)
