Maybe miss a year’s events, all but the last (4)
I believe the answer is:
anna
'maybe miss' is the definition.
(miss can refer to a woman)
'a year's events all but the last' is the wordplay.
'a year's events' becomes 'annal' (an annal is a record of a year's events).
'all but the last' means to remove the last letter.
'annal' with its last letter removed is 'ANNA'.
(Other definitions for anna that I've seen before include "Former Indian coin, girl" , "She's a woman, whichever way you look at it" , "The name's the same,either way" , "Unit of length" , "-- Wintour, editor" .)
