Intractable objections raised and brought forth (8)
I believe the answer is:
stubborn
'intractable' is the definition.
(similar in meaning)
'objections raised and brought forth' is the wordplay.
'objections' becomes 'buts' (as in 'no ifs, no buts').
'raised' says the letters should be written in reverse (going up in a down clue).
'and' means one lot of letters go next to another.
'brought forth' becomes 'born' (I've seen this in another clue).
'buts' reversed gives 'stub'.
'stub'+'born'='STUBBORN'
(Other definitions for stubborn that I've seen before include "Rigid" , "Obdurate and unyielding (8)" , "Obstinate, pig-headed" , "Unreasonably unwilling to change" , "Sticky" .)
