Praise from number of former partners outspoken? (5)
I believe the answer is:
extol
'praise' is the definition.
(extolling is a kind of praising)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for extol that I've seen before include "Highly rate" , "Praise highly, laud" , "Praise with enthusiasm" , "be lavish with praise" , "Praise - honour" .)
