Ancient Greek Alphabet

Greek alphabet only has 24 letters related to the Latin-based script that uses 26. However, the Greek alphabet has both uppercase and lowercase versions for all of them.

There are barely any characters that are not allowed in mathematics, science, and engineering. Greek alphabet or Greek letters are used to indicate various constants, values, and phenomena/particles. 

The Ancient Greek Alphabet has been in use from 750 BC to today. It is pleasing to note that the Greeks were the first Europeans to write an alphabet. Prior writing systems had been either syllabic or pictographic.

When was the Greek Alphabet Invented?

The Ancient Greece Alphabet over 2500 years old was not a Greek invention. It originated from the Phoenician alphabet.

The Greeks had position associations with the Phoenicians. Herodotus, the 5th-century Greek historian called the Greek letters “Phoenicia Grammata” meaning Phoenician letters.

Greek Alphabet

The Greek alphabet began making its presence after the Dark Ages. The first letter letters were Α (alpha), Ε (epsilon), Ι (iota), Ο (omicron), and Υ (upsilon). Greek also introduced three new consonant letters, Φ (phi), Χ (chi), and Ψ (psi), supplemented to the end of the alphabet as they were developed.

The Greek alphabet is a collection of twenty-four letters and it notes each vowel and consonant with a separate Greek symbol. The alphabet was written from right to left though it was written from left to right later.

The Greece Alphabet has two main sections. They were the Ionic and the Chalcidian. The Ionic or eastern, form was selected by Athens and became what we know today as the classical Greek alphabet. The Chalcidian or, western form, gave rise to the Etruscan alphabet that forms the base of the Latin or a Roman alphabet that we use today.

Greek Alphabets and Greek Sciences

Today, Greek alphabets are used in Greek abilities, mathematics, and physics. The Greek alphabet provided in addition to many other alphabets including Latin, the Gothic, and the Cyrillic.

Greek description is another large problem that may involve the works of the most prominent academics and philosophers of ancient Greek including Aristotle and Plato. The only Greece alphabet is bought with this topic.

The Greek Letters and Their Meanings

As one of the most famous and refined civilizations of earlier history, the culture of classical Greeks certainly left its mark on mankind’s progress. Today, we can see Greek symbols/letters extensively practiced in math and science. But what do they mean? For those who are curious to know, here is the Greek alphabet, a list of Greek symbols/Greek letters with their purposes.


Alpha (άλφα ) is the first letter of the Greek alphabet. Alpha is written as A in uppercase and α in lowercase. The alpha symbol is used to express many things including reflection factor, area, angles, and coefficients. It also has a strong spiritual meaning within the meaning it was used in the Bible lines when God made the declaration “I am the Alpha and Omega” as in “I am the source and the end of everything”.


Beta (βήτα) is the second letter in the Greek alphabet. Beta is written as B in uppercase and β in lowercase. In addition to coefficients and purposes, it is used to denote phase constants.


As the third one in our list of Greek letters/Greek symbols, gamma (γάμμα ) is written as Γ in uppercase and γ in lowercase. Gamma symbol issued to indicate multiplication constants, special gravity, electrical conductivity, and complex propagation constants between other things.


Delta (δέλτα ) is the fourth letter in the Greek alphabet It is written as Δ in uppercase and δ in lowercase. Delta symbol is applied to denote deflection in engineering, density, and angles along with other things in science.


Epsilon (έψιλον ) is the fifth letter of the Greek alphabet and it is written as Ε in uppercase and ε in lowercase. Epsilon symbol indicates dual numbers and the Heaviside step function in mathematics along with some other things in other controlled areas. Zeta The sixth Greek letter zeta (ζήτα ) is written as Ζ in uppercase and ζ in lowercase. The zeta symbol is applied to describe coefficients and coordinates in mathematics while it is used in polymer and liquid dynamics as well.


Eta (ήτα ) is the seventh letter in the Greek alphabet used to indicate coordinates, outside charge quantity, and natural impedance among other things. The uppercase letter is written as Η while the lowercase is η.


The eighth letter of the Greek alphabet, Theta (θήτα ) is written as Θ in uppercase and θ in lowercase. It is done to design time constant and angular phase displacement.


As the eleventh one in our list of Greek letters/symbols, lam(b)da (λά(μ)βδα ) is written as Λ in uppercase and λ in lowercase. The lambda symbol is issued to indicate the von Mangoldt faculty in mathematics while it can also be seen in areas such as physics, engineering, statistics, and even astronomy. On an interesting side note, the uppercase lambda symbol (Λ ) was used as the symbol of Spartans the renowned warriors of ancient times.


The sixteenth letter of the Greek alphabet, Pi (πι) is written as Π in uppercase and π in lowercase. The pi symbol is used to denote the real transcendental constant pi, more commonly known as the pi number (3.14159…) in mathematics, economic profit in macroeconomics, and osmotic pressure in chemistry among many other things throughout various scientific areas.


Rho (ρώ) is the seventeenth letter of the Greek alphabet written as Ρ in uppercase and ρ in lowercase. The rho symbol is used to represent coordinates, volume charge density, the prime constant, and the Rho protein among many other things. On a side note, it is the second part of the religious monogram, the chi-rho symbol (simply written as “XP”) used to represent Jesus Christ.


Sigma ( σίγμα) is the eighteenth Greek letter written as Σ uppercase and σ/ς or Ϲ ϲ in lowercase. The sigma symbol is used to denote sigma bonds (chemistry), the summation operator, velocity dispersion (astronomy), sigma receptor (biology), and sigma constant (chemistry) among other things.


Phi (φι) is the twenty-first letter in the Greek alphabet written as Φ in uppercase and φ in lowercase. The phi symbol represents the golden ratio in architecture and mathematics, magnetic flux in physics, and porosity in geology among many other things in science.


Omega (ωμέγα) is the twenty-fourth and last letter of the Greek alphabet written as Ω in uppercase and ω in lowercase. The omega symbol is used to denote the Omega constant, Caitlin's constant, solid angles, angular velocity, and Omega baryons among many other things in different areas of science.

It is also featured in logos of many companies such as Omega Watches SA and Pioneer as well as the famous action-adventure video game God of War (2018).


The Greek alphabet symbols and characters have a central position to be used as constants within the entire scientific arena from physicals and chemistry to more specific areas including electronics and electronics engineering.
