Fairy to dabble with musical instrument (10)
I believe the answer is:
'fairy' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'dabble with musical instrument' is the wordplay.
'dabble with' becomes 'tinker' (I can't explain this - if you can you should give a lot more credence to this answer).
'musical instrument' becomes 'bell' (bell is a kind of musical instrument).
'to' is the link.
Can you help me to learn more?
(Other definitions for tinkerbell that I've seen before include "Friend of Peter" , "JM Barrie's fairy" , "Fairy in "Peter Pan"" , "'Peter Pan' character" .)
