Man right to put up with rubbish (8)
I believe the answer is:
tommyrot
'rubbish' is the definition.
(I've seen this before)
'man right to put up' is the wordplay.
'man' becomes 'tommy' ().
'right' becomes 'r' (common abbreviation).
'put up' shows that the letters should be reversed in order.
'to' written backwards gives 'ot'.
'tommy'+'r'+'ot'='TOMMYROT'
'with' acts as a link.
(Other definitions for tommyrot that I've seen before include "Poppycock" , "Stuff and nonsense, baloney" , "Absolute rubbish, nonsense" , "tosh" , "Nonsense, rubbish - ask informal Thomas" .)
