Talk of going back to bed before tea, maybe (6)
I believe the answer is:
debate
'talk of' is the definition.
(thesaurus)
'bed before tea maybe' is the wordplay.
'before' means one lot of letters go next to another.
'maybe' indicates anagramming the letters.
'bed'+'tea'='bedtea'
'bedtea' is an anagram of 'DEBATE'.
'going back to' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for debate that I've seen before include "Public argument" , "Exchange of views" , "Verbal disputation" , "Discuss through argument" , "Ponder" .)
