She comes in and entertains us annually (5)
I believe the answer is:
susan
'she' is the definition.
'in and entertains us annually' is the wordplay.
'in' says the answer is hidden in the clue.
'SUSAN' is hidden in the letters of 'and entertains us annually'.
'comes' acts as a link.
(Other definitions for susan that I've seen before include "Girl (sometimes lazy?)" , "Girl's name, meaning lily" , "Girl's name; lazy -" , "-- Howatch, novelist" , "Black-eyed -; lazy -" .)
