Roman goddess of the hearth (5)
I believe the answer is:
vesta
'roman goddess of the hearth' is the definition.
(I've seen this before)
This is the entire 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" .)
