# Í

**Í** (lowercase **í**) is the Latin letter I carrying an acute accent (´), encoded in Unicode as U+00CD LATIN CAPITAL LETTER I WITH ACUTE, with the lowercase form at U+00ED.<sup>[1](https://unicodecharacter.com/characters/u-00cd)</sup><sup> • </sup><sup>[2](https://www.unicode.org/Public/UCD/latest/ucd/UnicodeData.txt)</sup> It is one of the precomposed accented letters of the Latin-1 Supplement block and is used in several European orthographies, most prominently Spanish, where í marks a stressed vowel.<sup>[1](https://unicodecharacter.com/characters/u-00cd)</sup><sup> • </sup><sup>[3](https://www.spanishdict.com/guide/how-to-pronounce-the-letter-i-in-spanish)</sup>

## Encoding and normalization

Í sits in the Latin-1 Supplement, the block immediately above the basic ASCII range, alongside the other precomposed accented vowels such as Á, É, Ó, and Ú.<sup>[1](https://unicodecharacter.com/characters/u-00cd)</sup> The character has existed since Unicode 1.1 in 1993, so it predates the large Latin Extended blocks that carry rarer combinations.<sup>[1](https://unicodecharacter.com/characters/u-00cd)</sup>

Like all precomposed accented letters, Í has a canonical decomposition. Under Normalization Form D (NFD) it splits into the base letter U+0049 I followed by the nonspacing combining acute accent U+0301; Normalization Form C (NFC) recombines that pair into the single code point U+00CD. The two spellings are canonically equivalent and should compare equal after normalization, which matters for string matching, searching, and deduplication in software.<sup>[1](https://unicodecharacter.com/characters/u-00cd)</sup> The Unicode Character Database records the same decomposition (0049 0301) together with the simple lowercase mapping to 00ED.<sup>[2](https://www.unicode.org/Public/UCD/latest/ucd/UnicodeData.txt)</sup>

A rendering detail specific to i is that a dotted i followed by a nonspacing mark above loses its dot, so í is drawn without the dot; the standard notes that an accented dotted-i is not equivalent to an accented dotless-i (for example, i + diaeresis is not the same as ı + diaeresis), a distinction that matters for Turkish and for dictionary typography.<sup>[5](https://www.unicode.org/versions/latest/ch07.pdf)</sup>

## Typing the character

Several input routes produce Í. In HTML and many programming contexts the named entity &Iacute; or the numeric reference &#x00CD; can be used; on Windows the [Alt code](https://www.edgepedia.org/alt-code) 0205 works on the numeric keypad.<sup>[4](https://www.key-shortcut.com/en/all-html-entities/aecoen-latin-letters)</sup> In Microsoft Word and WordPad, typing the hexadecimal code CD followed by Alt+X converts it to Í.<sup>[1](https://unicodecharacter.com/characters/u-00cd)</sup> On keyboards with dead keys, pressing the acute dead key and then Shift+I produces the capital form directly.

## Use in languages

The acute accent on i serves different purposes depending on the language. In Spanish, í marks that the vowel bears the word's stress, as in ídolo (idol), where the accent falls on the opening i; the pronunciation of the letter i itself varies very little across the Spanish-speaking world.<sup>[3](https://www.spanishdict.com/guide/how-to-pronounce-the-letter-i-in-spanish)</sup> [Reference](https://www.edgepedia.org/reference) works describe Í simply as the letter I with an acute accent, and it belongs to the wider family of acute-accented Latin capitals that includes Á, Ć, É, Ń, Ó, Ś, Ú, and Ź.<sup>[6](https://en.wiktionary.org/wiki/%C3%8D)</sup>

The acute-on-i combination is not limited to the single precomposed pair. Unicode also encodes rarer forms such as U+1E2E LATIN CAPITAL LETTER I WITH DIAERESIS AND ACUTE (Ḯ), used when a second diacritic stacks on top of the acute.<sup>[7](https://www.unicode.org/Public/UCD/latest/charts/nameslist/1e00/)</sup> Reference collections of accented i characters count 35 such characters in total across the standard, 17 lowercase and 18 capital and digraph forms, ranging from ì and î through į, ǐ, and ḯ.<sup>[8](https://accentcharacters.com/letters/i)</sup>

## Related letters

The other precomposed I letters of the Latin-1 Supplement cover different diacritics with different functions: Ì (U+00CC) with grave, Î (U+00CE) with circumflex, used in Dutch, French, and Romanian, and Ï (U+00CF) with diaeresis, used in Catalan, Dutch, and French.<sup>[9](https://op.europa.eu/en/web/eu-vocabularies/formex/physical-specifications/character-encoding/latin-letters)</sup> Further along the standard, Latvian uses Ī (U+012A) with macron and Lithuanian uses Į (U+012E) with ogonek, each listed for those languages in the EU Publications Office character specification.<sup>[9](https://op.europa.eu/en/web/eu-vocabularies/formex/physical-specifications/character-encoding/latin-letters)</sup>
