Girl is seen after the staff turns up (5)
I believe the answer is:
doris
'girl' is the definition.
(I've seen this before)
'is seen after the staff turns up' is the wordplay.
'seen after' means one lot of letters go next to another.
'the staff' becomes 'rod' (both can mean a pole or stick).
'turns up' says the letters should be written in reverse.
'rod' reversed gives 'dor'.
'is' after 'dor' is 'DORIS'.
(Other definitions for doris that I've seen before include "-- Day, actress" , "In Greek myth, wife of sea-god Nereus" , "Woman" , "Female name" , "Girl" .)
