greece-1594689_1920

The Ancient Greeks are known for their contributions to modern society. The Greeks are often thought of as the founders of philosophy, as well as early pioneers in literature, government, and more.

The Greeks were also one of the first to develop a comprehensive, written language that surfaced around the 8th century B.C,

and was used widely across the region.

Though the ancient Greek alphabet originally had multiple variants, The Euclidean Alphabet, which is still used today, has been used since the 4th century B.C. In addition to being used in the Greek language, Greek letters are also used as symbols in math and science, as well as in other fields. Below, we will go over the Greek letters as they’re used today, modern pronunciation, and their approximate English equivalents.

A Brief History of the Greek Alphabet


The Greek language was adapted from the earlier Phoenician and Semitic alphabet. Initially, the Greek alphabet used all the symbols from the Phoenician alphabet and adapted some to denote vowel sounds. The Greeks

added and dropped letters over time and changed their sounds and meaning

.

At first, the language used the same alphabet was pronunciations, and therefore dialects, differed by region, being separated into

Southern, Western, Eastern, and Classic

. The Southern dialect was most similar to the ancient Phoenician.

The way the letters were written were adapted over time as well. Originally, there were no uppercase letters. These were added in the late ninth century. They also changed what the letters were called to match the changing pronunciation. In this way, the Greek alphabet is very phonetic, and

you can see these phonetic influences in other languages

across the globe.

The same Greek alphabet is still used today, with some modifications in the letters and pronunciations.

Other Uses for Greek Alphabet Symbols


While you may not use the Greek alphabet symbols in your own language, you may recognize some of the letters from

math, science, and other labeling

. There are just a few common examples of where you might see Greek letters

A common example is the Greek letter Pi, which is a mathematical constant and is used as the ratio of a circle’s circumference to its radius. Pi is commonly shortened to “3.14”

Greek letters are also used in astronomy, to identify stars within a constellation. The biggest star in a constellation would be referred to as the Alpha, and the second biggest star as the beta and so forth.

Greek alphabet letters are also used in computer science and is an important part of some coding methods, such as Unicode.

Greek letters are also used often on college campuses by fraternities and sororities, and the

organizations are often referred to collectively as “Greek Life”

because they have adopted the alphabet as a naming technique, originally as a way to keep their organization a secret from non-members.
