Jersey perhaps is put on boy around November (6)
I believe the answer is:
island
'jersey perhaps' is the definition.
(Jersey is an island)
'is put on boy around november' is the wordplay.
'put on' is a charade indicator (letters next to each other).
'boy' becomes 'lad' (lad is a kind of boy).
'around' indicates putting letters inside.
'november' becomes 'n' (phonetic alphabet: alpha, bravo, charlie etc.).
'lad' enclosing 'n' is 'land'.
'is'+'land'='ISLAND'
(Other definitions for island that I've seen before include "I used for this" , "eg Jersey" , "See 15" , "Eg, eyot or inch" , "Body of land entirely surrounded by water" .)
