Star appearing in Love Games (4)
I believe the answer is:
vega
'star' is the definition.
(star in the constellation Lyra)
'in love games' is the wordplay.
'in' says the answer is hidden in the clue.
'VEGA' is hidden within 'love games'.
'appearing' acts as a link.
(Other definitions for vega that I've seen before include "First magnitude star" , "Fifth brightest star" , "heavenly body" , "Star in Lyra; grassy plain (Spanish)" , "Gave turn to a star" .)
