Bit of glue inside sealing circular patch (8,6)
I believe the answer is:
stamping ground
'patch' is the definition.
The definition and answer can be both locations as well as being singular nouns.
Maybe there's an association between them I don't understand?
'bit of glue inside sealing circular' is the wordplay.
'bit of glue' becomes 'stamping' (I can't explain this - if you can you should believe this answer much more).
'inside' means to look at the middle letters.
'sealing' becomes 'making tight' ('make tight' can be a synonym of 'seal').
'circular' becomes 'round' (synonyms).
The middle of 'makingtight' is 'g'.
'stamping'+'g'+'round'='STAMPING-GROUND'
Can you help me to learn more?
(Other definitions for stamping ground that I've seen before include "One's favourite area" , "making petulant gesture" , "seemingly petulant?" , "Displaying temper" , "Familiar position" .)
