They save the day for that woman from The Opposition losing the head (6)
I believe the answer is:
heroes
'they' is the definition.
Both the definition and answer are plural nouns.
Perhaps you can see an association between them that I don't see?
'save the day for that woman from the opposition losing the head' is the wordplay.
I cannot quite see how this works, but
'woman' could be 'her' and 'her' is found in the answer.
The remaining letters 'oes' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for heroes that I've seen before include "Brave people" , "Courageous people" , "Chief (male) characters of book, film, etc" , "men taking the lead" , "They show exceptional courage" .)
