Definition

What Is the Triple Prime Entity?

Triple Prime (‴) is the General Punctuation character at Unicode U+2034 (TRIPLE PRIME). HTML5 names it ‴. Use it for third derivatives and typographic triple-prime marks.

Remember

Character     ‴
Unicode       U+2034
Named entity  &tprime;
Hex entity    &#x2034;
Decimal       &#8244;
CSS escape    \2034
Not the same  &prime; (′) · &Prime; (″) · '''

Named, hex, decimal, CSS, and a typed character all produce the same glyph: ‴. Prefer ‴ in HTML markup. Pair with ′ and ″ for the prime series: f′, f″, f‴.

Reference

Quick Reference

One table for every form you will actually use.

Form	Code	Where it goes
Named entity	`‴`	HTML markup (best default)
Hex entity	`‴`	HTML markup
Decimal entity	`‴`	HTML markup
CSS escape	`\2034`	Stylesheet `content`
Direct character	`‴`	UTF-8 HTML text

When to Use Which

Situation	Use
Third derivative / triple prime	`‴` (preferred)
Numeric-only markup	`‴` or `‴`
Generated text via `::before` / `::after`	`content: "\2034"`
First / second prime	Use ′ or ″
Tempted to type `'''`	Use `‴` instead

Five ways to display ‴ in HTML and CSS.

html

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Triple Prime (‴)</title>
  <style>
    #point::after {
      content: "\2034";
    }
  </style>
</head>
<body>
  <p>Built with Named: &tprime;</p>
  <p>Built with Hex: &#x2034;</p>
  <p>Built with Decimal: &#8244;</p>
  <p id="point">Built with CSS: </p>
  <p>Typed: ‴</p>
  <p>Third derivative: f&tprime;(x)</p>
</body>
</html>

Try It Yourself

How It Works

1. Named: ‴ is the preferred HTML5 name for U+2034 → ‴.

2. Hex: ‴ inserts the same code point. Same visual as named.

3. Decimal: same code point as 8244 → ‴.

4. CSS: use \2034 in content (not an HTML entity). #point::after appends ‴.

5. Typed: paste ‴ in a UTF-8 document, or write f‴(x) for a third derivative.

Pitfalls & Tips

Common mistakes when working with Triple Prime.

Named

Prefer `‴`

‴ is the clear HTML5 named form. It is case-sensitive — write ‴, not &TPRIME;.

Look-alikes

‴ ≠ ′ ≠ ″ ≠ '''

U+2034 is one character. Do not fake it with three apostrophes. First and second primes use ′ and ″.

Add context

A lone ‴ may be unclear. Pair it with wording such as “third derivative” or an accessible name for screen readers.

Confusion

Not reverse prime or tilde

Do not confuse ‴ with reverse triple prime (‷) or triple tilde (≋) — different characters for different purposes.

CSS vs HTML

Do not mix escapes

\2034 belongs in CSS. ‴ / ‴ / ‴ belong in HTML.

Semicolon

End references

Always finish with ; — write ‴, not &tprime.

Compatibility

Triple Prime (U+2034) and its entity forms (‴, ‴, ‴, CSS \\2034) are supported in all modern browsers. Glyph coverage is strong in common fonts.

Remember

Key Takeaways

Unicode: this symbol is U+2034 (decimal 8244) — triple prime.
HTML: prefer ‴ — or use ‴ / ‴.
CSS: use \2034 inside content for generated prime marks.
Watch out: not the same as ′, ″, or three apostrophes.

One line: U+2034 → ‴ / ‴ / ‴ / CSS \2034.
