Cater basely (6)
I believe the answer is:
pander
'cater basely' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for pander that I've seen before include "Gratify wishes or weaknesses" , "Indulge or cater to" , "Indulge, gratify desires" , "Cater for vice or low tastes" , "Gratify weakness or base tastes" .)
