... put forward as low point, ultimately (4)
I believe the answer is:
moot
'put forward' is the definition.
(thesaurus)
'low point ultimately' is the wordplay.
'low' becomes 'moo' ('moo' can be a synonym of 'low').
'ultimately' indicates one should take the final letters.
The final letter of 'point' is 't'.
'moo'+'t'='MOOT'
'as' is the link.
(Other definitions for moot that I've seen before include "Open to argument or debate" , "raise for discussion" , "Propose for discussion" , "Subject to dispute" , "Questionable, debatable" .)
