ô on LaTeX: \^{o}

Ô on LaTeX: \^{O}

Or copy it:

Method 1: LaTeX command

Write \^{o} in text mode. Load \usepackage[T1]{fontenc} for correct hyphenation and copy-paste from the PDF.

Method 2: Type the character directly

Since 2018 pdfLaTeX reads UTF-8 by default, so you can paste ô into your source. On Overleaf, set the compiler in Menu → Compiler.

Method 3: In math mode

For a variable with this accent, use $\hat{o}$ . Math accents are for symbols, so use the text command for words.

The uppercase form works the same way with Shift added where a letter is typed.

About the letter ô

ô is Unicode U+00F4, named LATIN SMALL LETTER O WITH CIRCUMFLEX. It is used in French, Portuguese, Slovak, Welsh, Vietnamese and Afrikaans. A small caret (^) above a vowel. In French it often marks a vanished s (forêt from forest), in Portuguese a closed vowel, in Welsh a long vowel, and in Vietnamese a distinct vowel (â, ê, ô). See the ô character page for every code and shortcut.

Troubleshooting

Accents on i and j need the dotless forms \i and \j in old LaTeX; modern LaTeX handles this automatically.
If the letter is missing in the PDF, the font lacks it. Switch to XeLaTeX or LuaLaTeX with a broader font.
Wrap commands in braces when the next character is a letter: \'{e}x, not \'ex.
