November is a new month (5)
I believe the answer is:
nisan
'month' is the definition.
(month of the Hebrew calendar)
'november is a new' is the wordplay.
'november' becomes 'N' (phonetic alphabet: alpha, bravo, charlie etc.).
'new' becomes 'n' (abbreviation as in New Testament NT).
'n'+'is'+'a'+'n'='NISAN'
(Other definitions for nisan that I've seen before include "month in Israel" , "when Passover begins" .)
