Dignify (7)
I believe the answer is:
ennoble
'dignify' is the definition.
(I know that dignify can be written as ennoble)
This is all the clue.
(Other definitions for ennoble that I've seen before include "Distinguish" , "Bestow peerage on" , "Lend dignity or honour to" , "Confer dignity on" , "Raise to greater dignity" .)
