Rectify title (5)
I believe the answer is:
right
I believe this clue is a double definition.
'rectify' is the first definition.
(I've seen this before)
'title' is the second definition.
(thesaurus)
(Other definitions for right that I've seen before include "Most favourable" , "It's what you deserve" , "Correct; entitlement" , "Authority - one hand" , "Properly" .)
