The Seventh Letter of the Greek Alphabet: Its History and Meaning (7th)

The Greek alphabet is the basic unit of Greek writing. It consists of 24 letters, which are arranged in 5 groups. The Seventh Letter of the Greek Alphabet (ETA) is a symbol that was used by the ancient Greeks. It is the most widely used writing system in the world, and it was first invented in ancient Greece.

The Greek alphabet is the basis for most alphabets used today, including the Latin alphabet. It is also one of the oldest known alphabets, and it has been around since around the eighth century B.

In the present day, it is still used in countries such as:

  • Greece
  • Cyprus
  • Macedonia
  • Albania
  • Romania
  • Serbia
  • Bulgaria
  • Bosnia and Herzegovina.

As the language evolved, other languages started to use the Greek alphabet, too. Today, the Greek alphabet is also used in Turkish.

What is the Seventh Letter of the Greek Alphabet?

The letter ETA (uppercase Η, lowercase η) is the 7th letter of the Greek alphabet. It was first used in the Ionic alphabet. It is often represented by the symbol E. It’s sometimes written as a lowercase eta, but it’s also used as an uppercase ETA.

You should never confuse the capital Greek letter eta (Η) with the lowercase eta (η). In fact, you should write the word “Eta” in all caps, as shown “ETA”. However, you should write the word “eta” in italics, as shown “eta”.

Lowercase form of the Seventh Greek Letter

ETA was used in Ancient Greece and Rome to represent the sound /e/ or /ɛ/. The letter η (eta) is also used in the names of many other known letters, such as ι (iota), ε (epsilon), ζ (zeta), and ο (omicron).

What is its origin?

It has been found that the first person to use this letter was a Greek mathematician named Eta, who lived in the 4th century BC. He wrote a book called the Greek Syntax. It contains the Greek alphabet.

In the 6th century BC, the letter Eta (not necessary for the consonants in the eastern dialects of Greek, which lacked [h]) became the long vowel [ɛː], which was long used to evolve a new letter omega. During that period only ḥēth was retained as a consonant according to Greek, as one of the dialects of eta was [h] which represented the [h] sound. Whenever the vowels alpha o [o], and [a], e [e] become the consonants āleph, ʽayin, and hē respectively.

Eta used this letter as the first consonant of the second syllable of the word “heta”. A hetai is a long syllable in the Greek language that is written with the letter “h” and a vowel. By the 6th century BC the letter ETA came to stand for the long vowels, and a new letter, omega, was developed for long vowels.

Details History of Greek Letter ETA

Greek ETA or Ancient Greek: ē̂ta(uppercase Η, lowercase η) is the 7th letter of the Greek alphabet, It stands for the close front unrounded vowel (i). The classical Attic dialect of Ancient Greek had long open-mid front unrounded vowels calledIPA: [ɛː], raised toIPA: [i] in Hellenistic Greek, known as iotacism.

The Greek numerals eta represents 7 in the later system. The Phoenician letter heth is what inspired the name Eta. Latin H and the Cyrillic letter (И and Й) are examples of letters that came from eta.

What does it mean?

Eta is one of the most important letters in Greek. The letter η (“Eta”) is used to represent the sound i, which is an unrounded vowel. It has a higher frequency than i, as a result of its proximity to iota (ι). However, since it is unrounded, it is more similar to u than to i. The English letter ʹiʼ is sometimes called iota, after the ancient Greek letter iota / ι.

Eta is pronounced [i] when the letter is used in isolation, or in words starting with eta (etymonics). It is pronounced [ʒ] in words starting with heta (hetaonyms). In this case, the two syllables are pronounced as [hiːta] or [hiːˈtʰə] (with the accent over the second syllable).

Eta is also used in English words starting with eta (etymonics). It is pronounced [ɪˈtə] or [ɪˈtʰə].

There are also two different pronunciations for i in Modern Greek. One is IPA: [i] and the other is IPA: [ɪ]. The IPA: [ɪ] is closer to IPA: [ɨ] than IPA: [i] and IPA: [ɪ] is closer to IPA: [ɜ].

Use of Consonant h in Greek ETA

The etymological origin of the name of the letter ‘Eta’ comes from the Greek word “heta”. The first use of the ostrakon in the function of /h/ for Eta was by Hippocrates in 487 BC. The inscription on this caryatid is ΜΕΓΑΚLES HIΠΠΟΚRATOS. It is on display at the Ancient Agora Museum in the Stoa of Attalus.

Eta- In the function of /h/, a red-figured calyx-krater can be found in the Attic in 515 BC. There are two figures depicted, one is Hermes and the other is Hypnos. There are inscriptions: ΗΕΡΜΕΣ – ΗΥΠΝΟΣl.

Eta and the aspirate heta are both in use for a short period of time, but heta is gradually replaced by hētḗ. Eta also called Hetai or Heta, is a consonantal letter. It represents the sound /h/, in the International Phonetic Alphabet. It is not used for writing in most alphabets. However, it has been used in some languages as a grapheme in certain orthographies, such as English.

Heta (letter):

In most Greek dialects, the letter shape ‘H’ was used to represent the voiceless fricativeIPA: [h]. The Etruscan and other Old Italic alphabets were based on the Euboean form of the Greek alphabet and borrowed in the 8th century BC. The Latin alphabet was created with the letter H.

Some local Greek alphabets, called epichoric alphabets, used a variety of glyph forms for consonantal heta alongside the new vocalic eta for a while in dialects that still retained the sound IPA: [h]. The letter form was simplified to a “half-heta” in the southern Italian colonies of Heracleia and Tarentum, which were missing the right vertical stem.

There were other regional versions of the Greek alphabet that used different glyph shapes for vowels side by side with the new vocalic eta.

The heta also appears in the Greek alphabet (Etruscan, Ionic, and later Attic). It appears most commonly on Pamphylian (ancient Phrygian) coins and Etruscan vases from the second century BCE onwards.

In the modern Greek language, this sound has a number of different spellings depending on whether it is written with an uppercase or lowercase heta.

Long e:

According to the history of the East Ionic dialects, the sound IPA: [h] was lost in the sixth century BCE, and the letter was initially reused to represent the expansion of a long open front unrounded vowel IPA: [aː]. which later became one of the long open-mid front unrounded vowels in East Ionic instead of IPA: [ɛː].

Athens adopted the Ionian spelling system in 403 BC and with it the vocalic use of H (although it still had IPA: [h] at that time). After some time it became the standard orthography throughout Greece.


IPA: The [ɛː] sound was represented by “Eta” during Post-Classical Coin Greek. During that period many others were combined with previously distinct vowels. One of them is iotasism, also called itasism, but the new pronunciation eta is used instead of ETA in the name of this letter.

Itasism is used in Modern Greek, as [ˈita] where the letter name is pronounced, and IPA: [i], representing this unrounded vowel. which were also used to divide letters (υ, ι) and digraphs (ει, οι), which were also pronounced similarly.

Cyrillic script:

It is known that Eta carried the phonetic value of [i] in the Cyrillic script, where it gave rise to the Cyrillic letter “И”.

 The Letter i:

According to Modern Greek, the letter IPA: [i] (pronounced [ˈita]) represents a close front unrounded vowel due to iotacism. Also according to Classical Greek, IPA: represents [ɛː], which is also a long open-mid front unrounded vowel.

Use of Symbols of the Greek Alphabet ETA

Upper Case(H):

The capital letter Η is used as a textual criticism symbol for the Alexandrian text-type (coming from Hesychius, the supposed redactor).

In the language of chemistry, sometimes called the Greek eta, the letter H stands for enthalpy. Since enthalpy comes from “ἐνθάλπος”, which is from epsilon and starts smooth breathing, it is probably a Latin H for ‘heat’.

In information theory, the capital Greek letter H is used to represent the concept of entropy, as it is a discrete random variable.

Lower Case(η):

The letter η (lowercase) is used as a symbol:

In mathematics, the lowercase letter η is used in a few special cases. One of these cases is the case of the infinitesimal. The infinitesimal η is an infinitesimal quantity that is very small.

In physics, η represents the ratio of the energy density of an object to its mass density, and it is commonly written as. In fluid dynamics, it represents the ratio of shear stress to shear rate and is commonly written as. In engineering, it is used as the ideality factor of a bipolar transistor.

Power electronics η stands for the efficiency of a power supply, defined as the output power divided by the input power. In atmospheric science, η represents absolute atmospheric vorticity. Rheology, η represents viscosity.

Oceanography, η is the measurement (usually in meters) of sea-level height above or below the mean sea-level at that same location.

In telecommunications, η stands for the efficiency of a transistor. This is a value close to one. When it is close to one, the transistor is very efficient. When it is close to zero, the transistor isn’t very efficient.

When you use a transistor, you can make a lot of things happen with just a little amount of electricity. You can make a small radio station. You can also make a big radio station. You can also use a transistor to make the right decisions when you are buying stocks.
