Star article on vegetables (4)
I believe the answer is:
vega
'star' is the definition.
(star in the constellation Lyra)
'article on vegetables' is the wordplay.
'article' becomes 'a' (the indefinite article in English).
'on' is a charade indicator (letters next to each other).
'vegetables' becomes 'veg' (I can't explain this - if you can you should believe this answer much more).
'a' after 'veg' is 'VEGA'.
Can you help me to learn more?
(Other definitions for vega that I've seen before include "Star in Lyra; grassy plain (Spanish)" , "Fifth brightest star" , "Gave turn to a star" , "heavenly body" , "Brightest star of constellation Lyra" .)
