Which underlined word functions as a preposition in the sentence?

Question

The speaker looked around, and then spoke with a thunderous voice.

Answer 1

Prepositions and prepositional phrases function in multiple ways in a sentence.  They can be adverbs, adjectives, direct objects, or just plain prepositions.  There are about 50 common prepositions.  The word around is a preposition, but in this sentence it acts as a direct object as it receives the action. The only preposition in the word is with.  So the answer is with.

Answer 2

Hi Kevin;

WITH is the preposition.

As per the definition of preposition, a noun follows this.  It is also called the object of the preposition.  It is VOICE.
