Triple Prime Symbol
The triple prime (‴) is a punctuation mark commonly used to denote a third derivative or similar ordered notation.
U+2034
The symbol ‴ is called the Triple Prime. It’s a punctuation character with a specific Unicode code point, so it can be reliably copied or typed using its escapes.
Triple Prime Symbol Meaning
‴ (Unicode: U+2034), named TRIPLE PRIME, is a punctuation mark represented in HTML as ‴ and commonly written as the “triple prime.” In practice, it appears in ordered notation where one symbol level is not enough—most notably in contexts that use prime marks to indicate successive forms (for example, a third derivative). Because it’s a Unicode character rather than a plain ASCII approximation, using the real symbol helps documents, equations, and typography look consistent across fonts and platforms. When you need the “third” mark rather than a single prime (′) or double prime (″), triple prime is the correct choice.
Common uses
- •Denoting the third derivative in mathematical or scientific notation
- •Marking a third-level variant in technical documentation and specifications
- •Labeling layered revisions in engineering drawings or versioned annotations
- •Using it as a typographic punctuation marker in specialized scholarly writing
- •Rendering consistent notation in web apps using Unicode character support
