A. N. Other
A. N. Other is used as a placeholder name or, less commonly, used as a pseudonym by a person wishing to remain anonymous. It is most used in the United Kingdom, often written as AN Other. Occasionally it may be abbreviated to ANO, or—in cases where a female name is expected—rendered as Ann(e) Other. These various uses evoke the phrase, "an other", or the word, "another". A similarly constructed placeholder name, U. N. Owen, invokes the word "unknown".
