The Origin of Liar or Lier

The word liar comes from the verb “lie” (to tell something false). When forming a noun for a person, English adds “-ar” instead of “-er” in this case.

The spelling “lier” might look correct because many English words follow the -er pattern (like runner, writer). But “lie” is an exception.

👉 Key idea:
Not all English words follow the same rule.

The difference between liar and lier is simple once you understand the rule. Liar is the correct and standard word used to describe someone who tells lies. On the other hand, lier is either incorrect or extremely rare in modern usage, which makes it unsuitable for everyday writing.
