Ancient Greek is the form of the Greek language used during the periods of time spanning the c. 9th – 6th century BC, (known as Archaic), the c. 5th – 4th century BC ( Classical), and the c. 3rd century BC – 6th century AD ( Hellenistic) in ancient Greece and the ancient world. It was predated in the 2nd millennium BC by Mycenaean Greek. The language of the Hellenistic phase is known as Koine (common) or Biblical Greek, while the language from the late period onward features no considerable differences from Medieval Greek. Koine is regarded as a separate historical stage of its own, although in its earlier form, it closely resembled the Classical. Prior to the Koine period, Greek of the classic and earlier periods included several regional dialects.

Ancient Greek was the language of Homer and of classical Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the West since the Renaissance. This article primarily contains information about the Epic and Classical phases of the language.


The origins, early form and development of the Hellenic language family are not well understood because of the lack of contemporaneous evidence. There are several theories about what Hellenic dialect groups that may have existed between the divergence of early Greek-like speech from the common Proto-Indo-European language. They have the same general outline but differ in some of the detail. The only attested dialect from this period is Mycenaean, but its relationship to the historical dialects and the historical circumstances of the times imply that the overall groups already existed in some form.

*Dates (beginning with Ancient Greek) from Wallace, D. B. (1996). Greek Grammar Beyond the Basics: An Exegetical Syntax of the New Testament. Grand Rapids: Zondervan. p. 12. ISBN  0310218950. 

The major dialect groups of the Ancient Greek period can be assumed to have developed not later than 1120 BC, at the time of the Dorian invasion(s), and their first appearances as precise alphabetic writing began in the 8th century BC. The invasion would not be "Dorian" unless the invaders had some cultural relationship to the historical Dorians; moreover, the invasion is known to have displaced population to the later Attic-Ionic regions, who regarded themselves as descendants of the population displaced by or contending with the Dorians.

The Greeks of this period considered there to be three major divisions of all the Greek people—Dorians, Aeolians and Ionians (including Athenians), each with their own defining and distinctive dialects. Allowing for their oversight of Arcadian, an obscure mountain dialect, and Cyprian, far from the centre of Greek scholarship, this division of people and language is quite similar to the results of modern archaeological-linguistic investigation.

One standard formulation for the dialects is:

Distribution of Greek dialects in the classical period.
Western group:
   Doric proper
   Northwest Doric
Central group:
Eastern group:
   Achaean Doric
  • West Group
    • Northwest Greek
    • Doric
  • Aeolic Group
    • Aegean/Asiatic Aeolic
    • Thessalian
    • Boeotian
  • Ionic-Attic Group
    • Attica
    • Euboea and colonies in Italy
    • Cyclades
    • Asiatic Ionia
  • Arcadocypriot Greek
    • Arcadian
    • Cypriot

West vs. non-west Greek is the strongest marked and earliest division, with non-west in subsets of Ionic-Attic (or Attic-Ionic) and Aeolic vs. Arcado-Cyprian, or Aeolic and Arcado-Cyprian vs. Ionic-Attic. Often non-west is called East Greek.

The Arcado-Cyprian group apparently descended more closely from the Mycenaean Greek of the Bronze Age.

Boeotian had come under a strong Northwest Greek influence, and can in some respects be considered a transitional dialect. Thessalian likewise had come under Northwest Greek influence, though to a lesser degree.

Pamphylian, spoken in a small area on the south-western coast of Asia Minor and little preserved in inscriptions, may be either a fifth major dialect group, or it is Mycenaean Greek overlaid by Doric, with a non-Greek native influence.

Ancient Macedonian was an Indo-European language closely related to Greek, but its exact relationship is unclear because of insufficient data: possibly a dialect of Greek; a sibling language to Greek; or a close cousin to Greek, and perhaps related to some extent, to Thracian and Phrygian languages. The Pella curse tablet is one of many finds that support the idea that the Ancient Macedonian language is closely related to the Doric Greek dialect.

Most of the dialect sub-groups listed above had further subdivisions, generally equivalent to a city-state and its surrounding territory, or to an island. Doric notably had several intermediate divisions as well, into Island Doric (including Cretan Doric), Southern Peloponnesus Doric (including Laconian, the dialect of Sparta), and Northern Peloponnesus Doric (including Corinthian).

The Lesbian dialect was a member of the Aegean/Asiatic Aeolic sub-group.

All the groups were represented by colonies beyond Greece proper as well, and these colonies generally developed local characteristics, often under the influence of settlers or neighbors speaking different Greek dialects.

The dialects outside the Ionic group are known mainly from inscriptions, notable exceptions being fragments of the works of the poetess Sappho from the island of Lesbos and the poems of the Boeotian poet, Pindar.

After the conquests of Alexander the Great in the late 300's BC, a new international dialect known as Koine or Common Greek developed, largely based on Attic Greek, but with influence from other dialects. This dialect slowly replaced most of the older dialects, although Doric dialect has survived to the present in the form of the Tsakonian dialect of Modern Greek, spoken in the region of modern Sparta. Doric has also passed down its aorist terminations into most verbs of Demotic Greek. By about the 500's AD, the Koine had slowly metamorphosized into Medieval Greek.

See Proto-Greek for a description of sound changes from Proto-Indo-European up through attested Ancient Greek.


The pronunciation of Post-Classic Greek changed considerably from Ancient Greek, although the orthography still reflects features of the older language (see W. Sidney Allen, Vox Graeca – a guide to the pronunciation of Classical Greek). For a detailed description on the phonology changes from Ancient to Hellenistic periods of the Greek language, see the article on Koine Greek.

The examples below are intended to represent Attic Greek in the 5th century BC. Although ancient pronunciation can never be reconstructed with certainty, Greek in particular is very well documented from this period, and there is little disagreement among linguists as to the general nature of the sounds that the letters represented.

Sound changes


In verb conjugation, one consonant often comes up against the other. Various sandhi rules apply.


  • Most basic rule: When two sounds appear next to each other, the first assimilates in voicing and aspiration to the second.
    • This applies fully to stops. Fricatives assimilate only in voicing, sonorants do not assimilate.
  • Before an /s/ (future, aorist stem), velars become [k], labials become [p], and dentals disappear.
  • Before a /tʰ/ (aorist passive stem), velars become [kʰ], labials become [pʰ], and dentals become [s].
  • Before an /m/ (perfect middle first-singular, first-plural, participle), velars become [ɡ], nasal+velar becomes [ɡ], labials become [m], dentals become [s], other sonorants remain the same.

Compensatory lengthening

Certain vowels historically underwent compensatory lengthening in certain contexts. /a/ sometimes lengthened to [aː] or [ɛː], and /e/ and /o/ become the closed values [eː] and [oː] and the open ones [ɛː] and [ɔː] depending on time period.

Vowel shift

The Proto-Greek long vowel /aː/ was shifted to [ɛː] in the Attic dialect, except after /e i r/. In the Ionic dialect, it shifted in all environments, but in Doric and Aeolic, it did not shift at all.


Greek, like all of the older Indo-European languages, is highly inflected. It is highly archaic in its preservation of Proto-Indo-European forms. In Ancient Greek nouns (including proper nouns) have five cases ( nominative, genitive, dative, accusative and vocative), three genders ( masculine, feminine and neuter), and three numbers (singular, dual and plural). Verbs have four moods ( indicative, imperative, subjunctive, and optative), three voices (active, middle and passive), as well as three persons (first, second and third) and various other forms. Verbs are conjugated through seven combinations of tenses and aspect (generally simply called "tenses"): the present, future and imperfect are imperfective in aspect; the aorist ( perfective aspect); a present perfect, pluperfect and future perfect. Most tenses display all four moods and three voices, although there is no future subjunctive or imperative. Also, there is no imperfect subjunctive, optative or imperative. There are infinitives and participles corresponding to the finite combinations of tense, aspect and voice.


The indicative of past tenses adds (conceptually, at least) a prefix /e-/, called the augment. This was probably originally a separate word, meaning something like "then," added because tenses in PIE had primarily aspectual meaning. The augment is added to the indicative of the aorist, imperfect and pluperfect, but not to any of the other forms of the aorist (no other forms of the imperfect and pluperfect exist).

There are two kinds of augment in Greek, syllabic and quantitative. The syllabic augment is added to stems beginning with consonants, and simply prefixes e (stems beginning with r, however, add er). The quantitative augment is added to stems beginning with vowels, and involves lengthening the vowel:

  • a, ā, e, ē → ē
  • i, ī → ī
  • o, ō → ō
  • u, ū → ū
  • ai → ēi
  • ei → ēi or ei
  • oi → ōi
  • au → ēu or au
  • eu → ēu or eu
  • ou → ou

Some verbs augment irregularly; the most common variation is eei. The irregularity can be explained diachronically by the loss of s between vowels. In verbs with a prefix, the augment is placed not at the start of the word, but between the prefix and the original verb. For example, προσ(-)βάλλω (I attack) goes to προσέβαλoν in the aorist.

Following Homer's practice, the augment is sometimes not made in poetry, especially epic poetry.

The augment sometimes substitutes for reduplication; see below.


Almost all forms of the perfect, pluperfect and future perfect reduplicate the initial syllable of the verb stem. (Note that a few irregular forms of perfect do not reduplicate, whereas a handful of irregular aorists reduplicate.) There are three types of reduplication:

  • Syllabic reduplication: Most verbs beginning with a single consonant, or a cluster of a stop with a sonorant, add a syllable consisting of the initial consonant followed by e. An aspirated consonant, however, reduplicates in its unaspirated equivalent: Grassmann's law.
  • Augment: Verbs beginning with a vowel, as well as those beginning with a cluster other than those indicated previously (and occasionally for a few other verbs) reduplicate in the same fashion as the augment. This remains in all forms of the perfect, not just the indicative.
  • Attic reduplication: Some verbs beginning with an a, e or o, followed by a sonorant (or occasionally d or g), reduplicate by adding a syllable consisting of the initial vowel and following consonant, and lengthening the following vowel. Hence ererēr, ananēn, ololōl, ededēd. This is not actually specific to Attic Greek, despite its name; but it was generalized in Attic. This originally involved reduplicating a cluster consisting of a laryngeal and sonorant; hence h₃lh₃leh₃lolōl with normal Greek development of laryngeals. (Forms with a stop were analogous.)

Irregular duplication can be understood diachronically. For example, lambanō (root lab) has the perfect stem eilēpha (not *lelēpha) because it was originally slambanō, with perfect seslēpha, becoming eilēpha through compensatory lengthening.

Reduplication is also visible in the present tense stems of certain verbs. These stems add a syllable consisting of the root's initial consonant followed by i. A nasal stop appears after the reduplication in some verbs.

Writing system

Ancient Greek was written in the Greek alphabet, with some variation among dialects. Early texts are written in boustrophedon style, but left-to-right became standard during the classic period. Modern editions of Ancient Greek texts are usually written with accents and breathing marks, interword spacing, modern punctuation, and sometimes mixed case, but these were all introduced later.

Example text

The following polytonic Greek text is from the beginning of Apology by Plato:

Ὅτι μὲν ὑμεῖς, ὦ ἄνδρες Άθηναῖοι, πεπόνθατε ὑπὸ τῶν ἐμῶν κατηγόρων, οὐκ οἶδα: ἐγὼ δ' οὖν καὶ αὐτὸς ὑπ' αὐτῶν ὀλίγου ἐμαυτοῦ ἐπελαθόμην, οὕτω πιθανῶς ἔλεγον. Καίτοι ἀληθές γε ὡς ἔπος εἰπεῖν οὐδὲν εἰρήκασιν.

Transliterated into the Latin alphabet using a modern version of the Erasmian scheme:

Hóti mèn humeîs, ô ándres Athēnaîoi, pepónthate hupò tôn emôn katēgórōn, ouk oîda: egṑ d' oûn kaì autòs hup' autōn olígou emautoû epelathómēn, hoútō pithanôs élegon. Kaítoi alēthés ge hōs épos eipeîn oudèn eirḗkasin.

Using the IPA:

hóti men hymêːs, ɔ̂ː ándres atʰɛːnáioi, pepóntʰate hypo tɔ̂ːn emɔ̂ːn katɛːgórɔːn, oːk óida; egɔ̌ː dôːn kai autos hyp autɔ̂ːn olígoː emautôː epelatʰómɛːn, hǒːtɔː pitʰanɔ̂ːs élegon. kaítoi alɛːtʰés ge hɔːs épos eːpêːn oːden eːrɛ̌ːkasin.

Translated into English:

What you, men of Athens, have learned from my accusers, I do not know: but I, for my part, nearly forgot who I was thanks to them, since they spoke so persuasively. And yet, of the truth, they have spoken, one might say, nothing at all.

Another example, from the beginning of Homer's Iliad:

Μῆνιν ἄειδε, θεά, Πηληϊάδεω Ἀχιλῆος
οὐλομένην, ἣ μυρί’ Ἀχαιοῖς ἄλγε’ ἔθηκε,
πολλὰς δ’ ἰφθίμους ψυχὰς Ἄϊδι προΐαψεν
ἡρώων, αὐτοὺς δὲ ἑλώρια τεῦχε κύνεσσιν
οἰωνοῖσί τε πᾶσι· Διὸς δ’ ἐτελείετο βουλή·
ἐξ οὗ δὴ τὰ πρῶτα διαστήτην ἐρίσαντε
Ἀτρεΐδης τε ἄναξ ἀνδρῶν καὶ δῖος Ἀχιλλεύς.

Modern use

The study of Ancient Greek in European countries in addition to Latin occupied an important place in the syllabus from the Renaissance until the beginning of the 20th century. Ancient Greek is still taught as a compulsory or optional subject especially at traditional or elite schools throughout Europe, such as public schools and grammar schools in the United Kingdom. It is compulsory in the Liceo classico in Italy, in the gymnasium in the Netherlands, in some classes in Austria, in Croatia in klasicna gimnazija and it is optional in the Humanistisches Gymnasium in Germany (usually as a third language after Latin and English, from the age of 14 to 18). In 2006/07, 15,000 pupils studied Ancient Greek in Germany according to the Federal Statistical Office of Germany, and 280,000 pupils studied it in Italy. Ancient Greek is also taught at most major universities worldwide, often combined with Latin as part of Classics. It will also be taught in state primary schools in the UK, to boost children’s language skills, and will be offered as a foreign language to pupils in all primary schools from 2014 as part of a major drive to boost education standards, together with Latin, Mandarin, French, German, Spanish, and Italian. Ancient Greek is also taught as a compulsory subject in Gymnasia and Lykia in Greece.

Ancient Greek is often used in the coinage of modern technical terms in the European languages: see English words of Greek origin.

Modern authors rarely write in Ancient Greek, though Jan Křesadlo wrote some poetry and prose in the language, and some volumes of Asterix have been written in Attic Greek and Harry Potter and the Philosopher's Stone has been translated into Ancient Greek.

Ancient Greek is also used by organizations and individuals, mainly Greek, who wish to denote their respect, admiration or preference for the use of this language. This use is sometimes considered graphical, nationalistic or funny. In any case, the fact that modern Greeks can still wholly or partly understand texts written in non-archaic forms of ancient Greek shows the affinity of modern Greek language to its ancestral predecessor.

An isolated community near Trabzon, Turkey, an area where Pontic Greek is spoken, has been found to speak a variety of Greek that has parallels, both structurally and in its vocabulary, to Ancient Greek not present in other varieties. As few as 5,000 people speak the dialect but linguists believe that it is the closest living language to Ancient Greek.

Latinized forms of Ancient Greek roots are used in many of the scientific names of species and in scientific terminology.
