An individual for each lad (6)
I believe the answer is:
person
'an individual' is the definition.
('person' can be a synonym of 'individual')
'each lad' is the wordplay.
'each' becomes 'per'.
'lad' becomes 'son'.
'per'+'son'='PERSON'
'for' acts as a link.
(Other definitions for person that I've seen before include "anyone else" , "Individual human being" , "Type" , "character" , "Bod" .)
