To talk incessantly, that's all (5)
I believe the answer is:
total
'all' is the definition.
(thesaurus)
'to talk incessantly' is the wordplay.
'talk incessantly' becomes 'tal' (I can't explain this - if you can you should believe this answer much more).
'to'+'tal'='TOTAL'
'that's' acts as a link.
Can you help me to learn more?
(Other definitions for total that I've seen before include "Damage beyond repair" , "Aggregate, sum" , "Absolute; sum" , "The whole number" , "Reckon" .)
