Star not complete convert to compassionate eating? (4)
I believe the answer is:
vega
'star' is the definition.
(Vega is an example)
'not complete convert to compassionate eating?' is the wordplay.
'not complete' means to remove the last letter.
'convert to compassionate eating?' becomes 'vegan'.
'vegan' with its final letter taken off is 'VEGA'.
(Other definitions for vega that I've seen before include "Gave turn to a star" , "First magnitude star" , "Bright star of constellation Lyra" , "heavenly body" , "Brightest star of constellation Lyra" .)
