So this is the sentence:
He is killed.
Okay here in this sentence "killed" is the adjective that modifies the subject and "is" is the linking verb. Now what about if I want to say this:
He is killed by a car.
Now here killed is still an adjective and "by a car" is an prepositional phrase which acts like an adverb ? Am I right ? And if yes then what happens after that now the full thing "killed by a car" is an adjective that modifies the subject ?
