More than right (6)
I believe the answer is:
obtuse
'more than right' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for obtuse that I've seen before include "Angle between 90 and 180 degrees" , "To be thus blunt" , "'Dense, slow (6)'" , "Slow of understanding" , "Angle greater than 90 degrees" .)
