Roman goddess of the hearth (5)
I believe the answer is:
vesta
'roman goddess of the hearth' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for vesta that I've seen before include "heavenly body" , "Asteroid; goddess; match" , "Roman goddess; match" , "Stave (anag.)" , "Roman goddess of the hearth" .)
