Degree of warmth attending a kind of party (4)
I believe the answer is:
toga
'kind of party' is the definition.
(I've seen this in another clue)
'degree of warmth attending a' is the wordplay.
'degree of warmth attending' becomes 'tog' (I am not sure about this - if you are sure you should believe this answer much more).
'tog'+'a'='TOGA'
Can you help me to learn more?
(Other definitions for toga that I've seen before include "Roman tunic" , "Robe worn by Caesar" , "Got a cloak for an old Roman" , "Roman dress" , "Outer garment" .)
