Latin alphabetalso called Roman alphabetmost widely used alphabetic writing system in the world, the standard script of the English language and the languages of most of Europe and those areas settled by Europeans. Developed from the Etruscan alphabet at some time before 600 BC, it can be traced through Etruscan, Greek, and Phoenician scripts to the North Semitic alphabet used in Syria and Palestine about 1100 BC. The earliest inscription in the Latin alphabet appears on the Praeneste Fibula, a cloak pin dating from about the 7th century BC, which reads, “MANIOS MED FHEFHAKED NUMASIOI” (in Classical Latin: “Manius me fecit Numerio,” meaning “Manius made me for Numerius”). Dated not much later than this is a vertical inscription on a small pillar in the Roman Forum, and the Duenos inscription on a vase found near the Quirinal (a hill in Rome) probably dates to the 6th century BC. Although experts disagree on the dating of these objects, the inscriptions are generally considered to be the oldest extant examples of the Latin alphabet.

The classical Latin alphabet consisted of 23 letters, 21 of which were derived from the Etruscan alphabet. In medieval times the letter I was differentiated into I and J and V into U, V, and W, producing an alphabet equivalent to that of modern English with 26 letters. Some European languages currently using the Latin alphabet do not use the letters K and W, and some add extra letters (usually standard Latin letters with diacritical marks added or sometimes pairs of letters read as one sound).

In ancient Roman times there were two main types of Latin script, capital letters and cursive. There were also varieties of writing that mixed capitals and cursive or semicursive letters; Latin uncial script developed from such a mixed form in the 3rd century AD. In the Middle Ages many different Latin scripts developed from capital, cursive, and uncial forms. The round “humanistic” handwriting, used for copying books, and a more angular cursive script, used for legal and commercial purposes in 15th-century Italy, gave rise, respectively, to the roman and italic typefaces currently used in printing.
