Some lover totally unconcealed (5)
I believe the answer is:
overt
'unconcealed' is the definition.
(associated in meaning)
'some lover totally' is the wordplay.
'some' indicates the answer is hidden within the clue (some parts of the word are used).
'OVERT' can be found hidden inside 'lover totally'.
(Other definitions for overt that I've seen before include "Done or shown openly" , "Open,up front" , "not disguised" , "Conspicuous" , "Openly displayed" .)
