Still a day of anticipation before November (4)
I believe the answer is:
even
'still' is the definition.
(I know that still can be written as even)
'a day of anticipation before november' is the wordplay.
'a day of anticipation' becomes 'eve' (I've seen this in another clue).
'before' says to put letters next to each other.
'november' becomes 'N' (phonetic alphabet: alpha, bravo, charlie etc.).
'eve'+'n'='EVEN'
(Other definitions for even that I've seen before include "Level as odds may be" , "Level, par" , "without a rise?" , "Yet; level" , "Nearly" .)
