Elite group that's sometimes included in the bigger picture? (5)
I believe the answer is:
inset
'picture?' is the definition.
(I know that inset is a type of picture)
'elite group that's sometimes included in the bigger' is the wordplay.
I cannot quite see how this works, but
'group' could be 'set' (both can mean a collection) and 'set' is found in the answer.
'in' is present in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for inset that I've seen before include "Part of magazine" , "Small map within larger; teacher training day" , "Picture placed within another" , "Stein (anag)" , "Not taking proper care" .)
