Make easier, having second hint provided inside (8)
I believe the answer is:
simplify
'make easier' is the definition.
('simplify' can be a synonym of 'make easier')
'second hint provided inside' is the wordplay.
'second' becomes 's' (common abbreviation).
'hint' becomes 'imply' (I've seen this before**).
'provided' becomes 'if'.
'inside' is an insertion indicator.
'imply' enclosing 'if' is 'implify'.
's'+'implify'='SIMPLIFY'
'having' acts as a link.
(Other definitions for simplify that I've seen before include "Reduce in complexity" , "Streamline" , "Make accessible" , "Make less complex" , "Popularise" .)
