The dot on the letter i of the Latin alphabet originated as a diacritic to clearly distinguish i from the vertical strokes of the adjacent letters. It first appeared in the sequence ii (as in ingeníí) in Latin manuscripts of the 11th century, then spread to i adjacent to m, n, u, and later spread to all lower-case i. The j, which separated from the i later, inherited the "dot". The shape of the diacritic developed from initially resembling today's acute accent to a long flourish by the 15th century.

Alphabetization or collation

Different languages use different rules to put diacritic characters in alphabet

Alphabet

An alphabet is a standard set of letters—basic written symbols or graphemes—each of which represents a phoneme in a spoken language, either as it exists now or as it was in the past. There are other systems, such as logographies, in which each character represents a word, morpheme, or semantic...

ical order. French treats letters with diacritical marks the same as the underlying letter for purposes of ordering and dictionaries.

The Scandinavian languages, by contrast, treat the characters with diacritics ä, ö and å as new and separate letters of the alphabet, and sort them after z. Usually ä is sorted as equal to æ (ash) and ö is sorted as equal to ø (o-slash). Also, aa, when used as an alternative spelling to å, is sorted as such. Other letters modified by diacritics are treated as variants of the underlying letter, with the exception that ü is frequently sorted as y.

Languages that treat accented letters as variants of the underlying letter usually alphabetize words with such symbols immediately after similar unmarked words. For instance, in German where two words differ only by an umlaut, the word without it is sorted first in German dictionaries (e.g. schon and then schön, or fallen and then fällen). However, when names are concerned (e.g. in phone books or in author catalogues in libraries), umlauts are often treated as combinations of the vowel with a suffixed e; Austrian phone books now treat characters with umlauts as separate letters (immediately following the underlying vowel).

In Spanish, the grapheme ñ is considered a new letter different from n and collated between n and o, as it denotes a different sound from that of a plain n. But the accented vowels á, é, í, ó, ú are not separated from the unaccented vowels a, e, i, o, u, as the acute accent in Spanish only modifies stress

Stress (linguistics)

In linguistics, stress is the relative emphasis that may be given to certain syllables in a word, or to certain words in a phrase or sentence. The term is also used for similar patterns of phonetic prominence inside syllables. The word accent is sometimes also used with this sense.The stress placed...

Generation with computers

Modern computer technology was developed mostly in the English-speaking countries, so data formats, keyboard layouts, etc. were developed with a bias favoring English, a language with an alphabet without diacritical marks. This has led to fears internationally that the marks and accents may be made obsolete to facilitate the worldwide exchange of data. Efforts have been made to create internationalized domain names that further extend the English alphabet (e.g., "pokémon.com").

The rarer grave accent has the opposite effect, shortening vowel sounds that would usually be pronounced long.
