Indulge a bear, say (6)
I believe the answer is:
pander
'indulge' is the definition.
(I know that indulge can be written as pander)
'a bear say' is the wordplay.
'a bear' becomes 'panda'.
'say' shows a homophone (sound like).
'panda' is a homophone of 'PANDER'.
(Other definitions for pander that I've seen before include "Cater to lowest tastes" , "Indulge or cater to" , "Bow (to)" , "Gratify wishes or weaknesses" , "Give gratification (to)" .)
