Little boy led astray (3)
I believe the answer is:
del
'little boy' is the definition.
'Del' can be an answer for 'boy'. I'm not certain of the 'little' bit.
'led astray' is the wordplay.
'astray' indicates an anagram.
'led' anagrammed gives 'DEL'.
Can you help me to learn more?
(Other definitions for del that I've seen before include "Mathematical symbol < , delegate" , "- Boy (Only Fools and Horses)" , "drew it" , "Derek (dim.)" .)
