To make something straight; to remove bending or curvature from; a rare technical verb.
From 'deflexion' + '-ize' (to make or cause). This is an extremely rare formation, likely appearing only in highly specialized 19th-century medical or technical texts.
This word is so obscure that even many dictionaries don't include it—it might have been used by Victorian engineers or doctors trying to describe straightening procedures, but modern English uses simpler terms like 'straighten' or 'unbend' instead.
