In school we learn that to turn a verb into a noun we can simply add “er” onto the end. This is notably the case with professions such as singer, teacher and writer. That’s why it’s understandable that people make the mistake of turning the verb “to lie” into lier. This is incorrect if you’re referring to somebody who tells lies, but despite being frequently misused, it is actually a word in its own right.
A liar is a noun that comes from the verb “to lie” meaning to tell a lie, fabricate a story, make false statements, or simply not tell the truth. In short, it is a person who lies.
A lier, on the other hand, is a person who lies down or reclines. This noun comes from the verb “to lie” meaning to be in a horizontal position. Another sense of the word is slightly more specific, as it can refer to somebody who lies in wait or lies in ambush. It’s so rarely used that it doesn’t appear in many dictionaries, but it is included in some, including the Scrabble dictionary!
