Stupid to be moving us into it (6)
I believe the answer is:
obtuse
'stupid' is the definition.
('obtuse' can be similar in meaning to 'stupid')
'to be moving us into it' is the wordplay.
'moving' is an anagram indicator.
'into it' indicates putting letters inside.
'to'+'be'='tobe'
'tobe' is an anagram of 'obte'.
'obte' going around 'us' is 'OBTUSE'.
(Other definitions for obtuse that I've seen before include "A stupid angle?" , "Exaggerate" , "Orchestra; stripe" , "Angle greater than 90 degrees" , "Blunt, not sensitive" .)
