Other forms: precluded, precludes, precluding
To preclude is to make something impossible in advance. Preclude any doubt, precluded by the rules, this does not preclude it.
It is formal and belongs to rules and contracts, where something precluded is ruled out before it can arise. It is stronger than prevent, since preventing stops a thing happening and precluding stops it being possible.
