Lowercase y with acute (ý) is the Latin-1 Supplement character at Unicode U+00FD (LATIN SMALL LETTER Y WITH ACUTE). It is common in Czech, Slovak, Icelandic, Faroese, and other languages. HTML5 also defines the named entity ý.
Remember
Character ý
Unicode U+00FD
Named entity ý
Hex entity ý
Decimal ý
CSS escape \00FD
All of these produce the same glyph: ý. Prefer ý or a pasted ý in UTF-8 pages; use numeric or CSS forms when you need them.

How It Works
1. Named:ý is the HTML5 named entity for U+00FD. Clearest form in HTML source.
2. Hex:U+00FD → ý in HTML. Same glyph as named.
3. Decimal: same code point as 253 → ý. Same result.
4. CSS: use \00FD in content (not an HTML entity). #point::after appends that ý after the paragraph text.
Pitfalls & Tips
Common mistakes when working with the y acute entity.
Named
Prefer ý
HTML5 defines a named entity for this letter — use it for readable HTML.
CSS vs HTML
Do not mix escapes
\00FD belongs in CSS. ý / ý / ý belong in HTML.
Look-alikes
Not plain y
Plain y is U+0079. Acute is a different accented letter.
Case
ý vs Ý
Uppercase is U+00DD (Ý) — a different code point from U+00FD.
Semicolon
End references
Always finish with ; — write ý, not ý.
UTF-8
Declare charset
If you paste ý directly, serve the page as UTF-8 with <meta charset="UTF-8">.
