Character completing apprenticeship argued about raise (7)
I believe the answer is:
upgrade
'character completing apprenticeship' is the definition.
The definition and answer can be both human attributes as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'argued about raise' is the wordplay.
'argued' becomes 'grade' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'about' means one lot of letters go next to another.
'raise' becomes 'up' (I've seen this in other clues).
'grade' put after 'up' is 'UPGRADE'.
Can you help me to learn more?
(Other definitions for upgrade that I've seen before include "advance" , "Raise the level" , "Higher-standard version" , "promotion" , "Get better software" .)
