Question

Quizplus · Accepted Answer

The janitor moved swift through the many corridors of the building.
The word "swift" is an adjective and in this sentence, it's modifying the verb "moved", which is incorrect. Adjectives can't modify verbs, adverbs do. In this case, "swift" should be substituted by "swiftly."
The janitor did move swiftly through the many corridors of the building.
The auxiliary verbs do, does, and did can be followed by the bare infinitive in affirmative sentences to express emphasis, which is not needed in the context of this sentence.
The janitor did moved swiftly through the many corridors of the building.
The auxiliary verbs do, does, and did can be followed by the bare infinitive in affirmative sentences to express emphasis. In this sentence, "did" is followed by the past perfect "moved", which is not correct, and should be substituted by the infinitive "move."
