Many local variants of theGreek alphabet were employed inancient Greece during thearchaic andearly classical periods, until around 400 BC, when they were replaced by the classical 24-letter alphabet that is the standard today. All forms of the Greek alphabet were originally based on the shared inventory of the 22 symbols of thePhoenician alphabet, with the exception of the letterSamekh, whose Greek counterpartXi (Ξ) was used only in a subgroup of Greek alphabets, and with the common addition ofUpsilon (Υ) for the vowel/u,ū/.[1][2]The local, so-calledepichoric, alphabets differed in many ways: in the use of the consonant symbolsΧ,Φ andΨ; in the use of the innovative long vowel letters (Ω andΗ), in the absence or presence of Η in its original consonant function (/h/); in the use or non-use of certain archaic letters (Ϝ =/w/,Ϙ =/k/,Ϻ =/s/); and in many details of the individual shapes of each letter. The system now familiar as the standard 24-letter Greek alphabet was originally the regional variant of theIonian cities inAnatolia. It was officially adopted inAthens in 403 BC and in most of the rest of the Greek world by the middle of the 4th century BC.
A basic division into four major types of epichoric alphabets is commonly made according to their different treatment of additional consonant letters for the aspirated consonants (/pʰ,kʰ/) and consonant clusters (/ks,ps/) of Greek. These four types are often conventionally labelled as "green", "red", "light blue" and "dark blue" types, based on a colour-coded map in a seminal 19th-century work on the topic,Studien zur Geschichte des griechischen Alphabets byAdolf Kirchhoff (1867).[3][4] The "green" (or southern) type is the most archaic and closest to the Phoenician. The "red" (or western) type is the one that was later transmitted to the West and became the ancestor of theLatin alphabet, and bears some crucial features characteristic of that later development. The "blue" (or eastern) type is the one from which the later standard Greek alphabet emerged.
The "green" (southern) type uses no additional letters beyond the Phoenician set, and typically also goes withoutΞ (/ks/). Thus, the aspirated plosives/pʰ/,/kʰ/ are spelled either simply asΠ andΚ respectively, without a distinction from unaspirated/p/,/k/, or as digraphsΠΗ,ΚΗ. (However, for the analogous/tʰ/ there is already a dedicated letter,Θ, taken from Phoenician.) Likewise, the clusters/ps/,/ks/ are simply spelledΠΣ,ΚΣ. This is the system found inCrete and in some other islands in the southernAegean, notablyThera (Santorini),Melos andAnaphe.[5]
The "red" (western) type also lacks Phoenician-derivedΞ for/ks/, but instead introduces a supplementary sign for that sound combination at the end of the alphabet,Χ. In addition, the red alphabet also introduced letters for the aspirates,Φ =/pʰ/ andΨ =/kʰ/. Note that the use ofΧ in the "red" set corresponds to the letter "X" in Latin, while it differs from the later standard Greek alphabet, whereΧ stands for/kʰ/, andΨ stands for/ps/. OnlyΦ for/pʰ/ is common to all non-green alphabets. The red type is found in most parts of central mainland Greece (Thessaly,Boeotia and most of thePeloponnese), as well as the island ofEuboea, and in colonies associated with these places, including most colonies in Italy.[5]

*Upsilon is also derived fromwaw (
).

The "light blue" type still lacksΞ (/ks/), and adds only letters for/pʰ/ (Φ) and/kʰ/ (Χ). Both of these correspond to the modern standard alphabet. The light blue system thus still has no separate letters for the clusters/ps/,/ks/. In this system, these are typically spelledΦΣ andΧΣ, respectively. This is the system found inAthens (before 403 BC) and several Aegean islands.[5]
The "dark blue" type, finally, is the one that has all the consonant symbols of the modern standard alphabet: in addition toΦ andΧ (shared with the light blue type), it also addsΨ (at the end of the alphabet), andΞ (in the alphabetic position of Phoenician Samekh). This system is found in the cities of theIonian dodecapolis,Knidos in Asia Minor, and inCorinth andArgos on the northeastern Peloponnese.[5]
The lettereta (Η,
, originally calledhēta) had two different functions, both derived from the name of its Phoenician model,hēth: the majority of Greek dialects continued to use it for the consonant/h/, similar to its Phoenician value ([ħ]). However, the consonant/h/ was progressively lost from the spoken language (a process known aspsilosis), and in those dialects where this had already happened early on in the archaic period,Η was instead used to denote the long vowel/ɛː/, which occurred next in its name and was thus, in the/h/-less dialects, its naturalacrophonic value.[6] Early psilotic dialects include easternIonic Greek, theAeolic Greek ofLesbos, as well as theDoric Greek ofCrete andElis.[7]
The distribution of vocalicΗ andΕ differs further between dialects, because the Greek language had a system of three distincte-likephonemes: the longopen-mid/ɛː/ (classical spellingη), the longclose-mid/eː/ (classical spellingει), and the short vowel/e/ (classical spellingε). In the psilotic dialects ofAnatolia and adjacent eastern Aegean islands, as well asCrete, vocalicΗ was used only for/ɛː/. In a number of Aegean islands, notablyRhodes,Milos,Santorini andParos, it was used both for/h/ and for/ɛː/ without distinction. InKnidos, a variant letter was invented to distinguish the two functions:Η was used for/h/, and
for/ɛː/. In south Italian colonies, especiallyTaranto, after c. 400 BC, a similar distinction was made betweenΗ for/ɛː/, and
for/h/. This latter symbol was later turned into the diacritic sign forrough breathing by the Alexandrine grammarians.[6]
InNaxos the system was slightly different: here, too, the same letter was used for/h/ and for a long vowel, but only in those cases where a long e-like sound had arisen throughraising from older/aː/, not – as other users of vocalic eta did – also for the older/ɛː/ inherited from proto-Greek. This probably means that while in the dialects of other eta users the old and new longe had already merged in a single phoneme, the raising sound in Naxos was still distinct both from/aː/ and/ɛː/, hence probably an[æ]-like sound.[8]
Yet another distinction was found in a group of cities in the north-east of thePeloponnese, most notablyCorinth: here, it was not the open-mid/ɛː/ that was distinguished among the threee-sounds, but the closed-mid/eː/. The normal letter epsilon (Ε) was used exclusively for the latter, while a new special symbol
(or, inSicyon,
) stood both for short/e/ and for/ɛː/. Yet another variation of the system is found in neighbouringTiryns: it uses the letter forms of the Corinthian system,
versus E, but with the functional values of the classic eta versus epsilon system.[9]

| Rhodes, Melos, Thera, Paros | Η | Η | Ε | Ε | |

The letterDigamma (Ϝ) for the sound /w/ was generally used only in those local scripts where the sound was still in use in the spoken dialect. During the archaic period, this includes most of mainland Greece (except Attica), as well as Euboea and Crete. In Athens and in Naxos it was apparently used only in the register of poetry. Elsewhere, i.e. in most of the Aegean islands and the East, the sound /w/ was already absent from the language.[10]
The shape of the letter varies locally and over time. The most common early form is
. Over time it developed in analogy with Epsilon (which changed from
to "E"), becoming either the classical "F" or
. Early Crete had an archaic form
(which resembled its original model, the Y-shaped Phoenician waw
), or a variant with the stem bent sideways (
).[10]
Some local scripts used the M-shaped letterSan instead of standardSigma to denote the sound /s/. It is unclear whether the distinction between the two letters originally corresponded to different phonetic realizations of the /s/phoneme in different dialects. EpigrapherLilian Hamilton Jeffery (1915–1986) conjectured that San originally stood for a voiced [z] sound, and that thoseDoric dialects that kept San instead of Sigma may have had such a pronunciation of /s/.[11] Roger Woodard, professor ofclassics at theUniversity at Buffalo, hypothesizes that San may originally have stood for [ts].[12] In any case, each dialect tended to use either San or Sigma to the exclusion of the other, and while the earliestabecedaria listed both letter shapes separately in their separate alphabetic positions, later specimens from the sixth century onwards tend to list only one of them. San was used inArgos until the end of the 6th century,[13] inSicyon until c. 500,[14] inCorinth until the first half of the 5th century,[13] and in Crete for some time longer. Sicyon kept the sign as a local emblem on its coins.
The archaic letterKoppa or Qoppa (Ϙ), used for the backallophone of /k/ beforeback vowels [o, u], was originally common to most epichoric alphabets. It began to drop out of use from the middle of the 6th century BC. Some of the Doric regions, notably Corinth, Argos, Crete and Rhodes, kept it until the 5th century BC.[15]
A few letters have arisen from innovative letter distinctions, most of them for local alphabets.
The new letterOmega (Ω) to denote the long half-open[ɔː] sound was invented first in the East, in the Ionian cities of Asia Minor, at some time before 600 BC. It was created by breaking up the closed circle of the Omicron (Ο), initially near the side. The letter was subsequently turned upright and the edges curled outwards (
,
,
,
).
The Dorian city ofKnidos as well as a few Aegean islands, namelyParos,Thasos andMelos, chose the exact opposite innovation, using a broken-up circle for the short and a closed circle for the long/o/.[16]
Some Ionian cities used a special letter
, alphabetically ordered behindΩ, for a sibilant sound in positions where other dialects had eitherΣΣ orΤΤ (e.g.τέͳαρες 'four', cf. normal spelling Ionicτέσσαρες vs. Atticτέτταρες). This symbol later dropped out of alphabetic use, but survived in the form of the numeral symbolsampi (modernϡ). As an alphabetic character, it has been attested in the cities ofMiletus,[17]Ephesos,Halikarnassos,Erythrae,Teos (all situated in the region ofIonia inAsia Minor), in the island ofSamos, in the Ionian colony ofMassalia,[18] and inKyzikos (situated farther north in Asia Minor, in the region ofMysia). InPontic Mesembria, on the Black Sea coast ofThrace, it was used on coins, which were marked with the abbreviation of the city's name, spelledΜΕͲΑ.[19] The sound denoted by this letter was a reflex of the proto-Greek consonant clusters*[kj],*[kʰj],*[tj],*[tʰj], or*[tw], and was probably an intermediate sound during the phonetic change from the earlierplosive clusters towards the later/s/ sound, possibly anaffricate similar to/ts/.[20]
In one attested document, theArcadocypriot Greek ofMantinea used an innovative letter similar to И (
), probably derived from a variant ofsan, to denote what was probably a[ts]-like sound in environments reflecting etymologicalProto-Greek*/kʷ/.[21]
In the highly-divergentPamphylian Greek, the letterdigamma (Ϝ) existed side by side with another distinctive form
. It has been surmised that in this dialect the sound/w/ may have changed to labiodental/v/ in some environments. The F-shaped letter may have stood for the new/v/ sound, while the special И-shaped form signified those positions where the old/w/ sound was preserved.[22]
A special letter for a variant realization of the short/e/ sound,
, was briefly used in theBoeotian city ofThespiae in the late 5th century BC. It occurred in the place of normal epsilon (Ε) whenever the sound stood before another vowel. Since its shape suggests a compromise form between anΕ and anΙ, it is thought that it denoted araised allophone, approaching/i/. It is attested in only one document, a set of grave stelae from 424 BC.[23][24]
Many of the letters familiar from the classical Greek alphabet displayed additional variation in shapes, with some of the variant forms being characteristic of specific local alphabets.
The form ofΖ generally had a straight stem (
) in all local alphabets in the archaic period.Θ was mostly crossed (
or
).Ξ typically had a vertical stem (
), andΦ was most often
.Υ andΨ had frequent variants where the strokes branched out from the bottom of the character, resulting in
and
respectively.Η was originally a closed rectangular shape
and developed several variants with different numbers of arrangements of connecting bars between the two outer stems.[25]
The early shape ofΕ was typically
, with the arms diagonal and the stem descending below the lowest arm; it developed to the modern orthogonal formΕ during the archaic era. An analogous change was observed withϜ, which changed from
to either
orϜ. Early forms ofΜ typically had the left stem descending lower than the right stem (
); this remained a distinguishing feature in those varieties that also had san (
) for/s/.[26]
Π also typically had a shorter right stem (
). The top ofΠ could be curved rather than angular, approaching a Latin P (
). The GreekΡ, in turn, could have a downward tail on the right, approaching a Latin R. In many red varieties,Δ too had variants where the left stroke was vertical, and the right edge of the letter sometimes rounded, approaching a Latin D (
,
).[27]
The crooked shape ofΣ could be written with different numbers of angles and strokes. Besides the classical form with four strokes (
), a three-stroke form resembling an angular Latin S (
) was commonly found, and was particularly characteristic of some mainland Greek varieties including Attic and several "red" alphabets. The C-like "lunate" form ofΣ that was later to become the standard form in late antiquity and Byzantine writing did not yet occur in the archaic alphabets.[28]
The letterΙ had two principal variants: the classical straight vertical line, and a crooked form with three, four or more angular strokes (![]()
). The crooked type was the older form, and remained common in those varieties where it could not be confused with sigma because sigma was absent in favour of san.[29]
The lettersΓ andΛ had multiple different forms that could often be confused with each other, as both are just an angle shape that could occur in various positions. C-like forms ofΓ (either pointed or rounded) were common in many mainland varieties and in the West, where they inspired the Italic C; L-like shapes ofΛ were particularly common in Euboea, Attica and Boeotia.Achaean colonies had aΓ in the form of singleΙ-like vertical stroke.[30]
The letterΑ had different minor variants depending on the position of the middle bar, with some of them being characteristic of local varieties.[31]
The letterΒ had the largest number of highly divergent local forms. Besides the standard form (either rounded or pointed,
), there were forms as varied as
(Gortyn),
and
(Thera),
(Argos),
(Melos),
(Corinth),
(Megara,Byzantium),
(Cyclades).[31]
Κ,Ν,Ο andΤ displayed little variation and few or no differences from their classical forms.
All letters could additionally occur in a mirrored form, when text was written from right to left, as was frequently done in the earliest period.[32]
Athens, until the late 5th century BC, used a variant of the "light blue" alphabet, withΧΣ for/ks/ andΦΣ for/ps/.Ε was used for all three sounds/e,eː,ɛː/ (correspondinɡ to classicalΕ, ΕΙ, Η respectively), andΟ was used for all of/o,oː,ɔː/ (corresponding to classicalΟ, ΟΥ, Ω respectively).Η was used for the consonant/h/. Among the characteristics of Athens writing were also some variant local letter forms, some of which were shared with the neighbouring (but otherwise "red") alphabet ofEuboea: a form ofΛ that resembled a LatinL (
) and a form ofΣ that resembled a LatinS (
).[33]
By the late 5th century, use of elements of the Ionic alphabet side by side with this traditional local alphabet had become commonplace in private writing, and in 403 BC, a formal decree was passed that public writing would switch to the new Ionic orthography consistently, as part of the reform after theThirty Tyrants. This new system was subsequently also called the "Eucleidian" alphabet, after the name of thearchonEucleides who oversaw the decision.[34]

TheEuboean alphabet was used in the cities ofEretria andChalcis and in related colonies in southernItaly, notably inCumae,Pithecusae andRhegion. It was through this variant that the Greek alphabet was transmitted to Italy, where it gave rise to theOld Italic alphabets, includingEtruscan and ultimately theLatin alphabet. Some of the distinctive features of the Latin as compared to the standard Greek script are already present in the Euboean model.[35]
The Euboean alphabet belonged to the "western" ("red") type. It hadΧ representing/ks/ andΨ for/kʰ/. Like most early variants it also lackedΩ, and usedΗ for the consonant/h/ rather than for the vowel/ɛː/. It also kept the archaic lettersdigamma (Ϝ) for/w/ andqoppa (Ϙ) for/k/.San (Ϻ) for/s/ was not normally used in writing, but apparently still transmitted as part of the alphabet, because it occurs inabecedaria found in Italy and was later adopted by Etruscan.[35]
Like Athens, Euboea had a form ofΛlambda that resembled a Latin L and a form ofΣsigma that resembled a Latin S. Other elements foreshadowing the Latin forms includeΓgamma shaped like a pointed C (
),Δdelta shaped like a pointed D (
), andΡrho shaped like R (
).[35]

TheDoric dialect ofCorinth was written in a distinctive alphabet that belonged to the "eastern" ("dark blue") type as far as its treatment of/pʰ,kʰ,ps,ks/ was concerned, but differed from the Ionic and classical alphabet in several other ways. Corinth usedsan (Ϻ) instead ofΣ for/s/, and retainedqoppa (Ϙ) for what was presumably a retractedallophone of/k/ before back vowels. As described above, it also had an uncommon system for marking its[e]-sounds, with aΒ-shaped letter
used for/e/ and/ɛː/ (classicalΕ andΗ respectively), andΕ used only for long close/eː/ (classicalΕΙ). For the consonantΒ, in turn, Corinth used the special form
. The letterΙ was written like aΣ (
,
).[36]
