What is a Preposition?

1 min read
Share:

A preposition is a small word that shows a relationship between other words in a sentence. It often describes direction, location, time, or introduces an object.

Common Functions of Prepositions

  • Direction: I sent a letter to you.
  • Location: Someone is at the door.
  • Time: We will arrive by noon.
  • Introducing an object: She brought a basket of apples.

Prepositions are typically followed by an object — a noun, noun phrase, or pronoun.

Ending a Sentence with a Preposition

There is no rule in modern English that says a sentence cannot end with a preposition. This is a common myth from older grammar traditions. In fact, ending with a preposition can sound more natural and less formal.

  • This is the person I was talking about. ✅
  • This is the person about whom I was talking. 🧐 (Correct but formal or awkward)

💡 Tip

  • Prepositions often describe where, when, or how.
  • They’re usually followed by an object: to the store, in my bag, after lunch.
  • It’s okay to end a sentence with a preposition — if it sounds natural.
