Assign a time to praise (9)
I believe the answer is:
attribute
'assign' is the definition.
(I know that assign can be written as attribute)
'a time to praise' is the wordplay.
'time' becomes 't' (abbreviation).
'to praise' becomes 'tribute'.
'a'+'t'+'tribute'='ATTRIBUTE'
(Other definitions for attribute that I've seen before include "Quality, feature" , "Quality characteristic of person or thing" , "Ascribe, impute" , "Credit - property" , "A special characteristic" .)
