A striking redhead (5)
I believe the answer is:
vesta
'redhead' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'a striking' is the wordplay.
I cannot quite understand how this works, but
'a' is found in the answer.
The remaining letters 'vest' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for vesta that I've seen before include "Asteroid; goddess; match" , "Hearth goddess; a match" , "heavenly body" , "Roman goddess of the hearth" , "Roman goddess; match" .)
