Run along banks of canal like Van Gogh? (5,3)
I believe the answer is:
clear off
'run' is the definition.
The definition and answer can be both related to change as well as being verbs in their base form.
Maybe there's an association between them I don't understand?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for clear off that I've seen before include "Skedaddle" , "Begone (colloq.)" , "Leave" , "Go away - transparently" , "Run along!" .)
