You might have caught yourself thinking: “Wait, is it lier or liar?”
This is a common question because both words exist in English, but only one is correct when you’re talking about someone who tells lies.
Here’s the simple answer:
✅ Liar – the correct term for someone who tells lies
❌ Lier – incorrect in this context
It’s a small detail, but getting it wrong can make your writing look sloppy.
What Does “Liar” Mean?
A liar is:
👉 A person who deliberately tells falsehoods
Natural Examples:
- “He is a liar; you can’t trust anything he says.”
- “The politician was exposed as a liar.”
- “Don’t be a liar, tell the truth.”
It’s widely used in everyday conversation, literature, news, and social media.
What About “Lier”?
Lier technically exists in English, but it does not mean someone who tells lies.
- It can literally mean “someone or something that lies down”, though this usage is rare.
- In modern English, it is almost never used.
Example (very rare/technical):
- “A lier on the sofa will eventually get up.” ✅ (but sounds awkward)
Basically, in daily English, you never use “lier” for someone who tells lies.
