Leader of congregation has time to keep chattering (6)
I believe the answer is:
rabbit
'keep chattering' is the definition.
I can't tell whether this definition defines the answer.
'leader of congregation has time' is the wordplay.
'leader of congregation' becomes 'rabbi'.
'has' is a charade indicator (letters next to each other).
'time' becomes 't' (abbreviation).
'rabbi'+'t'='RABBIT'
'to' is the link.
Can you help me to learn more?
(Other definitions for rabbit that I've seen before include "may be pulled out of Derby, perhaps" , "Furry rodent" , "Fur; chatter (colloq.)" , "family pet?" , "Small mammal (not good at sports)" .)
