Answer: The object of a preposition is the noun or pronoun being acted on, referenced, or affected by the preposition in a prepositional phrase.
Explanation:
Prepositions express the relationship between a noun (or a word acting like a noun)—the object of the preposition—and another element of a sentence.
The relationships prepositions can show include physical position (about, above, below, on, and under), direction (in, into, to, toward), time (after, before, during, until), and source (from, of, out of).
Here are some example sentences using common prepositions (bold = preposition, italicized = object):
- The cat under the bed is sleeping quietly.
- We headed into the gallery opening after chatting outside.
- Before making a major decision, it’s a good idea to get enough sleep the night before.
- Would you mind stopping to pick up some bread from that bakery we love?
