Bench in class (4)
I believe the answer is:
form
I believe this is a double definition.
'bench' is the first definition.
(I've seen this before)
'class' is the second definition.
(I know that class can be written as form)
'in' acts as a link.
(Other definitions for form that I've seen before include "Configuration; type" , "Visible shape, class" , "Establish" , "Home of a hare" , "Criminal record (colloq.)" .)
