Gives, though is against, autographs (8)
I believe the answer is:
consigns
'gives' is the definition.
The definition and answer can be both to do with ownership as well as being verbs in their -s form.
Maybe you can see an association between them that I don't see?
'is against autographs' is the wordplay.
'is against' becomes 'con' (as in pros and cons, for and against).
'autographs' becomes 'signs' (I've seen this in another clue).
'con'+'signs'='CONSIGNS'
'though' is the link.
Can you help me to learn more?
(Another definition for consigns that I've seen is " Hands over, entrusts".)
