Cold boy clothed (4)
I believe the answer is:
clad
'clothed' is the definition.
(similar in meaning)
'cold boy' is the wordplay.
'cold' becomes 'c' (eg on taps).
'boy' becomes 'lad' (informal term for boy).
'c'+'lad'='CLAD'
(Other definitions for clad that I've seen before include "Wearing" , "Provided with covering" , "Invested" , "Cover with insulation" , "Attired" .)
