Thirteen loaves? (6,5)
I believe the answer is:
bakers dozen
'thirteen loaves?' is the definition.
(a baker's dozen means 13)
This is the entire clue.
(Other definitions for bakers dozen that I've seen before include "It might be a bloomer" , "Additional fare here" , "Thirteen loaves?" , "13" , "Unlucky number of loaves?" .)
