Man maybe is joined by boy around November (6)
I believe the answer is:
island
'man maybe' is the definition.
(Isle of Man is an example)
'is joined by boy around november' is the wordplay.
'joined by' means one lot of letters go next to another.
'boy' becomes 'lad' (lad is a kind of boy).
'around' means one lot of letters goes inside another.
'november' becomes 'n' (phonetic alphabet: alpha, bravo, charlie etc.).
'lad' placed around 'n' is 'land'.
'is'+'land'='ISLAND'
(Other definitions for island that I've seen before include "Possibly key" , "Ibiza maybe?" , "Body of land entirely surrounded by water" , "Pedestrian area in middle of road crossing" , "detached territory" .)
