Oathsign

Oathsign is a term that can refer to different concepts depending on context. In a general or ceremonial sense, an oath sign describes a symbol, gesture, or act associated with taking an oath. Examples include swearing with a hand raised, placing a hand on a sacred text, or other rituals that signify a pledge or commitment. The specific form of an oath sign varies across cultures, institutions, and legal traditions, and there is no single standardized practice.

In popular culture, Oath Sign is the title of a 2012 single by Japanese singer LiSA. The song served as the opening theme for the anime Fate/Zero. It was released as a single and has been included in LiSA’s discography, appearing on various editions and compilations. The track is notable within LiSA’s early career and is often associated with the Fate/ franchise in fan and media discussions.

The phrase Oath Sign or oathsign may also appear in discussions about branding or fictional works where a symbolic oath or pledge is a plot element. Because it can be written with or without a space, capitalization and styling may vary in different sources.
