Record left by girl (5)
I believe the answer is:
annal
'record' is the definition.
(I've seen this in another clue)
'left by girl' is the wordplay.
'left' becomes 'l' (common abbreviation).
'by' is a charade indicator (letters next to each other).
'girl' becomes 'anna' ().
'l' after 'anna' is 'ANNAL'.
(Other definitions for annal that I've seen before include "Year's entry in chronicle" , "Record of one year" , "Recorded event of one year" , "record shows" , "Yearly record" .)
