Titled little boy? (4)
I believe the answer is:
bart
'titled little boy?' is the definition.
'Bart' can be an answer for 'boy?'. I am not sure about the 'titled little' bit.
'titled little boy?' is the wordplay.
'titled little' becomes 'b' (I can't justify this - if you can you should give a lot more credence to this answer).
'boy?' becomes 'Art'.
'b'+'art'='BART'
Can you help me to learn more?
(Other definitions for bart that I've seen before include "Son in The Simpsons" , "Small title-holder being a brat" , "Homer's son" , "Branch of Islam" .)
