'murmurs constantly' is the definition.
The definition and answer can be both to do with communicating as well as being verbs in their -s form.
Maybe you can see an association between them that I don't see?

'graduate with books by the french' is the wordplay.
'graduate' becomes 'BA' (someone with a Bachelor of Arts degree).
'with' says to put letters next to each other.
'books' becomes 'BB' (two abbreviations for book).
'by' is a charade indicator (letters next to each other).
'the french' becomes 'les' (plural form of 'the' in French).
'ba'+'bb'+'les'='BABBLES'
