'want violin' is the definition.
The definition and answer can be both states of affairs as well as being singular nouns.
Perhaps they are linked in a way I don't understand?

'be plucked occasionally by daughter' is the wordplay.
'be' becomes 'exist' (synonyms).
'plucked' indicates the central letters (external letters removed as in plucking feathers).
'occasionally' becomes 'vo' (I can't explain this - if you can you should believe this answer much more).
'by' is a charade indicator (letters next to each other).
'daughter' becomes 'd' (genealogical abbreviation).
The middle letter of 'exist' is 'i'.
'i' put after 'vo' is 'voi'.
'voi'+'d'='VOID'

'to' is the link.

Can you help me to learn more?
