despolarizar

Primarily a technical term in physics, chemistry, and electronics meaning to remove polarization — despolarizar una célula (depolarize a cell membrane, in neuroscience/biology) or despolarizar la luz (depolarize light). It's increasingly borrowed into political journalism too, meaning to reduce polarization in a debate: despolarizar el discurso público.

• El estímulo nervioso despolariza la membrana celular. — The nerve stimulus depolarizes the cell membrane.
• El filtro despolariza la luz antes de que llegue al sensor. — The filter depolarizes the light before it reaches the sensor.
• El comentarista pidió despolarizar el debate político actual. — The commentator called for de-polarizing the current political debate.

Assuming despolarizar is purely a science word — its newer political-commentary sense (reducing polarization in public discourse) is now common in opinion journalism and shouldn't be dismissed as a misuse.
