Supporter of Elizabeth II? (8)
I believe the answer is:
seconder
'supporter of elizabeth ii?' is the definition.
'seconder' can be an answer for 'supporter' (seconder is a kind of supporter). I'm unsure of the 'of elizabeth ii?' bit.
'supporter of elizabeth' is the wordplay.
I cannot really understand how this works, but
'supporter' could be 'second' (second is a kind of supporter) and 'second' is found in the answer.
'elizabeth' could be 'er' and 'er' is present in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for seconder that I've seen before include "Supporter of a motion" , "Person supporting" , "One formally supporting" .)
