Languages of the Roman Empire: Latin, Greek, and Regional Speech

Latin supplied the language of Roman law and military records, while Greek served eastern provincial administration and educated exchange. Greek had spread through the eastern Mediterranean before Roman conquest. Residents also used regional languages, and scribes or interpreters helped people communicate with officials whose written language differed from their own.

The balance varied by place and period. Latin was especially important in western administration, Roman law and military records. Greek had already become a shared language of much of the eastern Mediterranean before Roman rule and remained central to its cities and government. Punic, a western variety of Phoenician spoken in Carthage, continued in North Africa; Egyptian developed into the forms now called Coptic, and Aramaic varieties were used widely in the East. Celtic, Germanic and other regional languages also survived, often with much less written evidence.

Latin and Greek in imperial government

Latin held a privileged position in central Roman institutions. Greek was extensively used in eastern official correspondence and administration. Officials translated documents or arranged for them to be read aloud when needed.

Administration and military service encouraged Latin use, alongside commerce and education. Caracalla extended citizenship to nearly all free inhabitants in AD 212. Regional languages continued among the newly enfranchised population.

Greek occupied a different but equally important position. Koine Greek, the widely used form of Greek that developed after the conquests of Alexander the Great, was already common around the eastern Mediterranean and in Asia Minor. Roman officials used it in the East, and educated members of the Roman elite often studied it. Greek was valuable in diplomacy, trade, literature, philosophy, and the administration of eastern communities. The linguistic boundary between the Latin-speaking West and Greek-speaking East ran broadly through the Balkan region, although it was never a rigid frontier.

Members of the imperial court could use both languages. The emperor Claudius referred to Latin and Greek as Rome’s two languages and maintained separate imperial secretaries for them. Bilingual inscriptions show how the languages operated together: a soldier’s epitaph might be written mainly in Greek while giving his rank and military unit in Latin. In the eastern provinces, laws and official documents were regularly translated from Latin into Greek, and both languages remained active in government and the Church during the fifth century.

Latin in public life and the army

Documents show both Latin’s prestige and the practical need for other languages. Roman citizens’ wills in Egypt were traditionally drawn up in Latin; a ruling under Severus Alexander in the early third century permitted Greek. Professional scribes could prepare documents for people who lacked the required language or writing skills.

Ulpian recognised trusts expressed in Greek, Punic, Gaulish or other languages. Verbal obligations raised questions about mutual understanding between the parties. Requirements depended on the legal act and its procedure, as explained in Roman law.

Latin was especially important in military commands, titles and record keeping, even in regions where Greek or local languages predominated. Soldiers recruited from different communities could speak other languages among themselves or with their families. Latin military terminology also survived in the Eastern Roman Empire as Greek became increasingly dominant.

Roman institutions also communicated without relying entirely on literacy or a shared spoken language. Religious ceremonies, public monuments, and images expressed imperial ideas to diverse populations. Pantomime, a performance tradition associated with Greek performers, used gesture rather than spoken dialogue and became popular across the multilingual empire.

Regional languages under Roman rule

Bilingual inscriptions, personal names and loanwords record contact between languages. References to interpreters identify situations where speakers needed assistance. Literary works survive in some regional languages, while others are known chiefly through inscriptions and occasional words.

Aramaic and Syriac

Aramaic was widely spoken in Syria and Mesopotamia in several varieties. Syriac developed as a literary form of Aramaic associated especially with Edessa and its region, and became a major language of eastern Christianity. Biblical translations, hymns, theological writing and other works gave it a substantial literary tradition.

Greek, Aramaic, and Syriac could coexist in the same communities. The Syrian writer Bardesanes knew Greek but chose to write in Syriac, while works by Ephraim were translated into Greek.

Coptic and Egyptian languages

Coptic represents the latest written stage of Egyptian. It used an alphabet largely based on Greek, supplemented by signs derived from Demotic for Egyptian sounds, while Demotic itself was a cursive script used to write Egyptian. Earlier experiments and differing local practices preceded its extensive literary use in late antiquity. Sahidic, Bohairic, Fayumic and other dialects show that Egyptian speech was not uniform.

Coptic was used for Christian scripture, letters, monastic texts and practical documents, including transactions. Greek remained the main language of much of Roman Egypt’s administration, while Latin had narrower official and military uses. After the Arab conquest in the seventh century, administrative and everyday language practices changed gradually. Coptic continued in documentary as well as religious use for centuries.

Punic in North Africa

Punic continued in North Africa after the destruction of Carthage and the establishment of Roman rule. Neo-Punic inscriptions include religious dedications, tombstones and public texts. At places such as Leptis Magna, Punic and Latin could appear in the same civic environment.

Punic was also written in Latin characters. Augustine referred to Punic-speaking communities in late antiquity, documenting its continued use in North Africa alongside Latin.

Celtic languages in the West

Celtic languages included Gaulish in Gaul, Celtiberian and Gallaecian in parts of Hispania, Brittonic in Britain, and Galatian in Anatolia. Their written evidence is uneven. Celtiberian inscriptions appear after contact with Rome in the second century BC, and some record hospitium, a custom of pledging mutual support between families or communities. Celtiberians continued to make such tokens while increasingly switching to Latin. Written Celtiberian disappeared around the beginning of the imperial period.

Gaulish survived much longer in speech. References by Christian writers, jurists, and physicians indicate that it remained useful for communication, contracts, prophecy, traditional medicine, and magic. The bishop Irenaeus of Lugdunum, writing in the second century AD, referred to the need to address some parishioners in their local language. Evidence from late antique writers suggests that Gaulish may have continued in parts of France into the sixth century, even as spoken Latin developed into Gallo-Romance varieties.

In Britain, inscriptions and writing tablets reveal Latin in military, administrative, commercial and personal settings, while Brittonic continued to be spoken. The scale of everyday bilingualism and the survival of spoken Latin after Roman government ended remain debated. In the western Pyrenees, the ancestors of Basque also survived long contact with Latin.

Germanic and ancient Balkan languages

Germanic-speaking communities were present both beyond and within the empire, and military service created opportunities for contact with Latin. Gothic is much better recorded than many early Germanic languages because parts of a fourth-century Bible translation survive in later manuscripts.

Thracian, Dacian and Illyrian are known unevenly through names, brief inscriptions and isolated words. Their distribution and relationships cannot be reconstructed fully from this material. Albanian contains early Latin loans, although its relationship to particular ancient Balkan languages is disputed.

Multilingual identities and communities

Babatha’s archive contains documents dated AD 93–132 in Greek, Jewish Aramaic and Nabataean Aramaic. They concern property, family affairs and petitions in the region incorporated into Roman Arabia. Some Greek documents carry signatures or subscriptions in Aramaic scripts.

The tombstone of Regina, associated with Arbeia at South Shields, identifies her as a woman of the British Catuvellauni and the freedwoman and wife of Barates from Palmyra. Her commemoration records a household linking Britain with an eastern merchant’s origins. The stone is preserved as a museum object.

Jewish communities likewise used more than one language. Inscriptions from across the diaspora appear in Greek and Latin, while Hebrew and Jewish Aramaic remained important in religious and communal settings. In Jewish communities of the eastern provinces, Greek could coexist with Hebrew and Aramaic. The Greek translation of the Hebrew Bible and Jewish works written in Greek show how the language served audiences within and beyond Jewish society.

Language opportunities also depended on movement, family resources and access to learning. The articles on Roman demography and migration and Roman education explore those settings.

Language, Christianity, and ritual

Greek’s wide circulation helped Christian ideas move across the eastern Mediterranean and beyond. The New Testament was written in Greek, and Greek was the original language of the letters of Paul and of the records of the major Christian councils. During the first half of the fifth century, bishops commonly communicated in Greek, after which council records were translated into Latin, Syriac, or Coptic for other communities.

Latin had a subordinate position at these eastern councils, although it remained central to the Christian West. Constantine used Latin at his court and required an interpreter when addressing Greek-speaking bishops at the Council of Nicaea. Christian identity was not restricted to a single language, and by late antiquity Christian literature existed in many of the languages used throughout the empire.

Ritual practice could preserve unusual combinations of languages. Magical texts and amulets often joined Greek, Egyptian, Hebrew, Aramaic, Latin, and local languages. The Greek Magical Papyri, a collection of spells, rituals and hymns from Greco-Roman Egypt, date from the second century BC to the fifth century AD. They contain Greek and Demotic Egyptian passages, as well as strings of words intended to be pronounced even when their meaning was unclear. Some rituals treated exact wording as part of their effectiveness, so a language could survive in spells or healing practices after losing much of its everyday use.

From imperial languages to later languages

In the western provinces, spoken Latin developed into regional varieties that became Romance languages. French, Spanish and Italian arose through these local developments, while Romanian preserves a separate eastern Romance history. Latin continued in law, scholarship and western churches.

Greek increasingly dominated eastern Roman administration. Syriac and Coptic retained substantial Christian literary traditions, while other regional languages disappeared from writing or remained sparsely recorded. Surviving inscriptions and manuscripts document specific communities and uses.
