Group going around gallery with Will? (7)
I believe the answer is:
testate
'will?' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'group going around gallery' is the wordplay.
'group' becomes 'set' (both can mean a collection).
'going around' shows that the letters should be reversed in order.
'gallery' becomes 'tate' (Tate Modern, Tate Britain etc).
'set' reversed gives 'tes'.
'tes'+'tate'='TESTATE'
'with' acts as a link.
Can you help me to learn more?
(Other definitions for testate that I've seen before include "With a legally valid will" , "Having made a will before death" , "Having written a valid will" , "Having made a last will and testament" , "Person willing" .)
