Liar – A Person Who Tells Lies

Liar is the common word you know. It means someone who does not tell the truth.

Examples:

  • He’s such a liar, nobody believes him.
  • Don’t trust a liar with important secrets.
  • The child was called a liar for making up the story.
  • She accused him of being a liar in front of everyone.
  • That politician turned out to be a liar.

👉 Tip: If you mean a dishonest person, always use liar.

Lier – Rare and Old-Fashioned

Lier is almost never used today. It means “someone who lies down.” Most people will never see this word outside of old books or poetry.

Examples:

  • The soldier was a lier in wait for the enemy.
  • The cat, a lazy lier on the couch, ignored everyone.
  • In the old text, the word lier meant someone lying down.

👉 Tip: You probably don’t need to use lier in modern English. Use lying down instead.

Quick Trick to Remember

  • Liar = tells lies (dishonest person).
  • Lier = lies down (rare, outdated word).

Example in one sentence:

  • The liar told everyone a false story, while the dog was a lier on the floor.
