Possibly meant to take in to repair and for alteration (9)
I believe the answer is:
amendment
'for alteration' is the definition.
'possibly meant to take in to repair' is the wordplay.
'possibly' is an anagram indicator.
'to take in' is an insertion indicator.
'to repair' becomes 'mend' ('mend' can be a synonym of 'repair'**).
'meant' is an anagram of 'ament'.
'ament' going around 'mend' is 'AMENDMENT'.
'and' is the link.
(Other definitions for amendment that I've seen before include "maybe fifth taken by US criminal" , "Correction" , "Addition or alteration, to a motion or official document, say" , "the fifth one benefiting Uncle Sam's defendants?" , "Change designed to improve a text" .)
