One for writing notes home? (3)
I believe the answer is:
pad
'home?' is the definition.
(pad can mean someone's home)
'one for writing notes' is the wordplay.
'one for writing' becomes 'p' (I can't explain this - if you can you should believe this answer much more).
'notes' becomes 'ad' (two musical notes).
'p'+'ad'='PAD'
Can you help me to learn more?
(Other definitions for pad that I've seen before include "Walk with soft steady steps" , "Sole" , "Block of paper sheets" , "Absorbent material" , "Fill with extra material in order to lengthen" .)
