Impostor and imposter are both correct English spellings. They have the same meaning and are used to describe someone who pretends to be another person, often to gain an advantage or deceive others. The main difference is spelling preference, not meaning.

Definition and Meaning
An impostor/imposter is someone who falsely presents themselves as another person.
For example:
The man claimed to be a doctor, but he was an impostor.
The word can also describe someone who pretends to have a position, identity, skill, or status that they do not actually have.
The two spellings have the same definition.
The Origin of Impostor and Imposter
The word impostor comes from Latin imponere, meaning to impose or place upon. It passed through French and other European languages before entering English.
The Latin related form influenced the spelling impostor.
The spelling imposter developed as an English spelling variant. The ending er is very common in English nouns describing people who perform an action.
For example:
- teach → teacher
- write → writer
- sing → singer
- act → actor
Because English speakers often expect words referring to people to end in er, imposter became a natural spelling.
Why Are There Two Spellings?
English contains many words with more than one accepted spelling. This can happen because of:
- Historical spelling changes
- Different language influences
- Regional preferences
- Pronunciation patterns
- Simplification of older spellings
- Dictionary and editorial preferences
Impostor preserves the traditional form, while imposter follows a spelling pattern that feels more natural to many English speakers.
