In contrast, lier is a rare word used for someone who lies down or lies in wait. Most people confuse these two because they sound identical, but their meanings differ significantly. Using the wrong word can make your writing sound strange or incorrect to readers.

The Short Answer

A liar is a person who tells lies; lier is a rare word for one who lies down or lies in wait.

Frequently Asked Questions

When should I use lier instead of liar?

You should only use lier when you mean someone who is lying down or lying in wait. If you are talking about a person telling untruths, you must use the word liar. Using lier for a person who tells lies is a common spelling mistake.

Is liar a noun or an adjective?

Liar is a noun that names a specific type of person. You can call someone a liar, but you cannot say someone is a liar unless you are labeling them directly. It describes the role of the person rather than describing a characteristic.

Why do people spell it lier by mistake?

People often spell it lier because the word lie is the root verb. They assume the person who lies down or tells lies should share the same spelling pattern. However, the silent 'e' at the end changes the meaning entirely in this specific case.
