She may be burning to give you a light (5)
I believe the answer is:
vesta
'a light' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'she may be burning' is the wordplay.
I cannot really see how this works, but
'she' could be 'esta' and 'esta' is found within the answer.
A single letter 'v' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'to give you' acts as a link.
Can you help me to learn more?
(Other definitions for vesta that I've seen before include "Hearth goddess; a match" , "Asteroid; goddess; match" , "Stave (anag.)" , "Roman goddess of the hearth" , "heavenly body" .)
