Record left by girl (5)
I believe the answer is:
annal
'record' is the definition.
(I've seen this before)
'left by girl' is the wordplay.
'left' becomes 'l' (common abbreviation).
'by' says to put 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" .)
