Stars as a central character in Greek mythology (9)
I believe the answer is:
andromeda
'stars' is the definition.
(Andromeda is a constellation)
'a central character in greek mythology' is the wordplay.
I cannot really see how this works, but
'a' could be 'an' and 'an' is found within the answer.
'character' could be 'r' and 'r' is found in the answer.
This explanation may well be incorrect...
'as' is the link.
Can you help me to learn more?
(Other definitions for andromeda that I've seen before include "Galaxy nearest ours" , "Large northern constellation between Perseus and Pegasus" , "group of stars" , "Pattern of stars" , "Constellation; bog rosemary" .)
