Suggest I take up no attitude (8)
I believe the answer is:
position
'attitude' is the definition.
(I know that attitude can be written as position)
'suggest i take up no' is the wordplay.
'suggest' becomes 'posit' (I've seen this before).
'take up' says the letters should be written backwards (I've seen 'taken up' mean this).
'no' in reverse letter order is 'on'.
'posit'+'i'+'on'='POSITION'
(Other definitions for position that I've seen before include "Place where something is" , "Place or perspective" , "Office - location" , "Put" , "Stance" .)
