Passive voice
VerbsRule 9 of 10
The rule
The passive is be + past participle: "The email was sent." Only verbs that take an object can go passive; happen, occur, appear, and sleep cannot, so "was happened" is always wrong. When you know who did the action, the active form is usually clearer: "I made a mistake", not "A mistake was made by me." One case runs the other way: "born" needs the passive: "I was born in Seoul."
