For each young lad there is somebody (6)
I believe the answer is:
person
'somebody' is the definition.
(I've seen this in another clue)
'for each young lad' is the wordplay.
'for each' becomes 'per' (per person).
'young lad' becomes 'son' (a young boy).
'per'+'son'='PERSON'
'there is' is the link.
(Other definitions for person that I've seen before include "Bod" , "See 17" , "Type" , "anyone else" , "present appearing in this" .)
