Current fashion runs over November (6)
I believe the answer is:
modern
'current' is the definition.
(associated in meaning)
'fashion runs over november' is the wordplay.
'fashion' becomes 'mode' (synonyms).
'runs' becomes 'r' (cricket abbreviation).
'over' is a charade indicator (letters next to each other).
'november' becomes 'N' (phonetic alphabet: alpha, bravo, charlie etc.).
'mode'+'r'+'n'='MODERN'
(Other definitions for modern that I've seen before include "Belonging to the present time" , "Belonging to the present or recent times" , "The very latest available" , "'Contemporary, up-to-date (6)'" , "Of the present time or current fashion" .)
