Give daughter a note perhaps (6)
I believe the answer is:
donate
'give' is the definition.
(donating is a kind of giving)
'daughter a note perhaps' is the wordplay.
'daughter' becomes 'd'.
'perhaps' indicates anagramming the letters.
'a'+'note'='anote'
'anote' is an anagram of 'onate'.
'd'+'onate'='DONATE'
(Other definitions for donate that I've seen before include "Give (transplant organ)" , "Make a contribution" , "Give as a gift as to charity" , "Give freely, maybe blood" , "Give to a charity or good cause" .)
