Typing í (i with acute) on LaTeX takes a few seconds once you know the trick. The short answer is \'{\i}. Read on for step-by-step instructions, the uppercase Í and what to do when a method does not work.

í on LaTeX: \'{\i}

Í on LaTeX: \'{I}

Or copy it:

Method 1: LaTeX command

Write \'{\i} 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 í into your source. On Overleaf, set the compiler in Menu → Compiler.

Method 3: In math mode

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

About the letter í

í is Unicode U+00ED, named LATIN SMALL LETTER I WITH ACUTE. It is used in Spanish, Portuguese, Italian, Czech, Slovak, Hungarian, Icelandic and Dutch. A short line slanting up to the right. It marks stress in Spanish (canción), a closed vowel in French (été), vowel length in Czech, Hungarian and Irish, and a rising tone in Vietnamese and Pinyin. See the í 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.
