Allow female relative time (5)
I believe the answer is:
grant
'allow' is the definition.
(I know that allow can be written as grant)
'female relative time' is the wordplay.
'female relative' becomes 'gran' (short for grandmother).
'time' becomes 't' (abbreviation).
'gran'+'t'='GRANT'
(Other definitions for grant that I've seen before include "Subsidy" , "Permit" , "Make" , "Agree to - bursary" , "Confer" .)
