Silly Billy from New York receiving accommodation (5)
I believe the answer is:
ninny
'silly billy' is the definition.
(I've seen this before)
'new york receiving accommodation' is the wordplay.
'new york' becomes 'ny'.
'receiving' is an insertion indicator.
'accommodation' becomes 'inn' (an inn accommodates guests).
'ny' going around 'inn' is 'NINNY'.
'from' acts as a link.
(Other definitions for ninny that I've seen before include "Silly billy" , "Fool" , "gravely so miscalled by mechanicals" , "dope" , "not a wise man" .)
