Definition:
An asterisk (*) is a typographical symbol used in writing and printing as a reference mark or to indicate omission, doubtful matter, or annotations. It is commonly placed beside a word, phrase, sentence, or number to direct the reader to a footnote or endnote that provides additional information or clarification. Asterisks are also used in mathematics, computing, and other fields for different purposes, such as multiplication, wildcard matches, or denoting significant figures.
Etymology & Origin:
The word “asterisk” comes from the Late Latin “asteriscus,” meaning “little star,” which in turn is derived from the Greek “asteriskos.” The Greek term is a diminutive of “astēr,” meaning “star.” The symbol’s use dates back to ancient manuscripts, where it was employed by scribes in textual annotations. Over time, the asterisk has evolved to serve multiple functions across various disciplines.
Examples:
- Footnotes and References: In academic and literary texts, an asterisk signals a footnote that provides further explanation or cites sources.
- Omissions: Asterisks are used to omit letters in a word, often for the purpose of anonymizing names or censoring offensive language.
- Mathematics and Computing: In programming, the asterisk can represent multiplication or function as a wildcard character that stands in for unknown or variable characters.
