Noun
passivization (countable and uncountable, plural passivizations)
(US, grammar) The process of rendering into the passive form.
Not all languages have a passive voice, and some that do have one (e.g. Polish ) don't allow the indirect object of a ditransitive verb to be promoted to subject by passivization, as English does. Source: Internet
In others like Dutch a passivization is possible but requires a different auxiliary: "krijgen" instead of "worden". Source: Internet
