Bank arrest? (3)
I believe the answer is:
nab
This might be a double definition.
'bank' is the first definition.
The definition and answer can be both to do with contact as well as being verbs in their base form.
Perhaps you can see a link between them that I can't see?
'arrest?' is the second definition.
('nab' can be a synonym of 'arrest')
Can you help me to learn more?
(Other definitions for nab that I've seen before include "Apprehend" , "Catch (thief) (colloq.)" , "Catch (a felon)" , "Collar (sl.)" , "Run in" .)
