In the end, run over to collect honour: it precedes Oscar (8)
I believe the answer is:
november
'it precedes oscar' is the definition.
(N before O in NATO Phonetic Alphabet)
'in the end run over to collect honour' is the wordplay.
'in the end' says to take the final letters.
'to collect' means one lot of letters goes inside another.
'honour' becomes 'mbe' (**).
The final letter of 'run' is 'n'.
'over' placed around 'mbe' is 'ovember'.
'n'+'ovember'='NOVEMBER'
(Other definitions for november that I've seen before include "Ninth month in the Roman calendar" , "Eleventh month" , "N in radio comms" , "Taunt, food in trap" , "date" .)
