Little Susan not last in canal (3)
I believe the answer is:
sue
This might be a double definition.
'little susan' is the first definition.
(I've seen this before)
'last in canal' is the second definition.
Although both the answer and definition are verbs in their base form, I can't see how they can define each other.
'not' acts as a link.
Can you help me to learn more?
(Other definitions for sue that I've seen before include "Make a legal claim" , "Charge" , "Litigious girl" , "take to 10 [COURT] !" , "Entreat; girl's name (dim.)" .)
