Boy has little time for this county (4)
I believe the answer is:
kent
'for this county' is the definition.
(Kent is an example)
'boy has little time' is the wordplay.
'boy' becomes 'ken' (man's name).
'has' says to put letters next to each other.
'little time' becomes 't' (abbreviation for time).
'ken'+'t'='KENT'
(Other definitions for kent that I've seen before include "Home county" , "English garden" , "Earl Lear banishes" , "County of SE England" , "Canterbury's county" .)
