Provided note with greeting (4)
I believe the answer is:
gave
'provided' is the definition.
(giving is a kind of providing)
'note with greeting' is the wordplay.
'note' becomes 'g' (musical note).
'with' is a charade indicator (letters next to each other).
'greeting' becomes 'ave' (Latin greeting).
'g'+'ave'='GAVE'
(Other definitions for gave that I've seen before include "Yielded; hosted (a party)" , "Buckled" , "Yielded under pressure" , "Handed over" , "Contributed" .)
