What Is the Lowercase R Tail Entity?

Lowercase r with tail (ɽ) is the Unicode character at U+027D in IPA Extensions. Official name: LATIN SMALL LETTER R WITH TAIL — the letter r with a rightward hook (tail), used in IPA for the retroflex flap (common in Indic languages).

Hex + Decimal + CSS + Typed

Four ways to display ɽ in HTML and CSS.

html
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Lowercase R Tail (ɽ) in HTML</title>
  <style>
    #point::after {
      content: "\027D";
    }
  </style>
</head>
<body>
  <p>Built with Hex: &#x27D;</p>
  <p>Built with Decimal: &#637;</p>
  <p id="point">Built with CSS: </p>
  <p>Typed: ɽ</p>
  <p>IPA sample: [&#x27D;]</p>
</body>
</html>
Try It Yourself

How It Works

1. Hex: U+027D → &#x27D; in HTML. The browser turns it into ɽ.

2. Decimal: same code point as 637 → &#637;. Same result as hex.

3. CSS: use \027D in content (not an HTML entity). #point::after appends ɽ.

4. Typed: paste ɽ in a UTF-8 document for IPA text. There is no named entity — numeric form is required when you need an entity.

Pitfalls & Tips

Common mistakes when working with lowercase r with tail.

Named?

No named entity

HTML5 does not define a named entity for U+027D. Use &#x27D; or &#637;.

Look-alikes

Not plain r or fishhook

Plain r is U+0072. ɻ is the retroflex approximant. ɽ is the retroflex flap — different manners of articulation.

Fonts

Need IPA Extensions coverage

Some fonts omit IPA Extensions. Prefer a font that includes U+027D for reliable glyphs.

CSS

Pad the CSS escape

Prefer \027D (four hex digits). A short \27D can swallow the next hex digit if one follows immediately.

CSS vs HTML

Do not mix escapes

\027D belongs in CSS strings. &#x27D; / &#637; belong in HTML.

Purpose

Not for body copy

Use plain r in normal English sentences. Reserve ɽ for phonetic transcription.

Semicolon

End references

Always finish entities with ; — write &#x27D;, not &#x27D.

Browser Support

Lowercase r with tail (U+027D) and its entity forms (&#x27D;, &#637;, CSS \\027D) are supported in all mainstream browsers. Visible glyphs depend on IPA Extensions font coverage.

✓ Universal support

Lowercase R Tail (&#x027D;)

Encode with hex, decimal, CSS escape, or type the character — same code point everywhere encoding is supported.

Bottom line: Prefer &#x27D; or &#637; in HTML when encoding must be explicit, and \\027D only inside CSS content. There is no named entity.

Key Takeaways

  • Unicode: lowercase r with tail is U+027D (decimal 637) — glyph ɽ.
  • HTML: use &#x27D; or &#637; — no named entity.
  • CSS: use \027D inside content for generated text.
  • Watch out: ɽ ≠ plain r ≠ ɻ (fishhook / approximant).

One line: U+027D → &#x27D; / &#637; / CSS \027D (no named entity).

Frequently Asked Questions

Use &#x27D; (hex), &#637; (decimal), type ɽ in UTF-8, or the CSS escape \027D in content. There is no HTML5 named entity for U+027D.
U+027D (LATIN SMALL LETTER R WITH TAIL). Hex 27D, decimal 637. It belongs to IPA Extensions (U+0250–U+02AF).
No. HTML5 does not define a named entity for this character. Use numeric references like &#637; or &#x27D; when you need an entity form.
Use it for IPA phonetic transcription of the retroflex flap (common in Indic languages), linguistic dictionaries, and language-learning content that needs ɽ. Prefer plain r for ordinary English spelling.
HTML entities (&#637; or &#x27D;) go in markup. The CSS escape \027D goes in stylesheet strings (usually content on ::before/::after).
No. Plain r is U+0072. R with fishhook ɻ (U+027B) is the retroflex approximant. R with tail ɽ (U+027D) is the retroflex flap — different manners of articulation.

Did you know?

Lowercase r with tail is Unicode U+027D (decimal 637) — LATIN SMALL LETTER R WITH TAIL in IPA Extensions. HTML5 has no named entity for it — use &#x27D; or &#637;. In IPA it marks the retroflex flap (many Indic languages). Not the same as plain r or r with fishhook ɻ.
