Has he pounds in pocket money? (5)
I believe the answer is:
colin
'has he' is the definition.
'Colin' can be an answer for 'he'. I'm not certain of the 'has' bit.
'pounds in pocket money?' is the wordplay.
'pounds' becomes 'l' (L can represent the monetary pound).
'in' is an insertion indicator.
'pocket money?' becomes 'coin' (I am not sure about this - if you are sure you should believe this answer much more).
'l' going inside 'coin' is 'COLIN'.
Can you help me to learn more?
(Other definitions for colin that I've seen before include "--- Wilson, Eng. writer (The Outsider)" , "Man's name" .)
