Latin script (Roman script)

Origins and historical development

The basic letter shapes of the Latin script trace back to adaptations of the Greek alphabet. A western Greek variety influenced the alphabets of peoples in the Italian peninsula; the Etruscans further adapted those signs before they reached the Romans. For this development see discussions of the Greek alphabet and the role of the Etruscans. Over centuries the Roman capitals evolved alongside cursive and book hands, and medieval scribes produced a range of regional styles that later fed into modern typography.

Structure and key characteristics

The classical Latin script distinguishes a set of graphic signs commonly called letters. In modern use the number of distinct letters and auxiliary signs varies by language: English uses 26 basic letters, while other languages add diacritics, special letters or digraphs. A defining feature is the pair of case forms—upper (capital) and lower (small) letters—which were standardized gradually; modern capital letter shapes remain close to Roman inscriptions and are the subject of typographic tradition (capitals).

• Letter case: separate uppercase and lowercase forms.
• Modifications: diacritics (e.g., accents, cedillas), additional letters and digraphs used by many languages.
• Typeface diversity: serif and sans-serif families, calligraphic hands, and modern digital fonts.

Geographic spread and languages

The Latin script is the principal script for most languages of Western Europe and many beyond. It is used throughout much of the Americas, Sub-Saharan Africa, Southeast Asia, and parts of Oceania. Examples of non-European languages that adopted or adapted the Latin script include Turkish, Vietnamese, Malay, Swahili and Filipino/Tagalog. In some regions it coexists with other scripts: Serbian and Bosnian may use both Cyrillic and Latin conventions (Serbian, Bosnian). The script's global spread was accelerated by trade, missions, colonial expansion and modern education systems; see general surveys of modern languages that employ it.

Uses, notation and technology

Beyond native orthographies, the Latin script is widely used for international transliteration, scientific names (binomial nomenclature), technical standards and information systems. Computer encodings such as ASCII and Unicode include extensive representations of Latin letters and their variants, allowing global interchange of text. The script's compatibility with typewriters, printing presses and digital devices helped make it a default choice for many international and technical contexts.

Distinctions, adaptations and notable facts

Some important points of distinction: "Latin alphabet" can mean the set of core letters inherited from classical Latin, while "Latin script" often refers more broadly to all graphic conventions, diacritics and letterforms derived from that tradition. Regional adaptations produce significant diversity—orthographies differ in how they represent sounds, whether they use accents or special letters, and how they order letters. Typography and orthographic reform have repeatedly shaped modern alphabets, and the Latin script continues to evolve as languages adapt it to new sounds and needs.

For further reference and comparative details consult materials on general writing systems and language orthographies via resources such as writing systems, surveys of language use, and individual language pages including Turkish, Vietnamese, Malay, Swahili, Serbian, Bosnian, and broader alphabet histories at Greek and Etruscan studies. Typography and the use of capitals remain important topics in design and legibility research.
